....but I very rarely leave them in 'Park' as if (say) they are 'nudged' heavily whilst parked out on public roads/car parks that would damage the gearbox
Really? From the gearboxes I am familiar with I find that hard to believe.

Just out of sheer laziness and insufficient caffein this morning I will just copy/paste this from t'internet....

Your automatic transmission has a device known as a parking pawl. This device locks the transmissions output shaft, preventing it from moving when your shifter is in Park. This device resembles a pin, that functions by engaging a notched ring attached to the transmission's output shaft when in 'PĒ Park position
To my mind - any collision (even a fairly low speed one) could either snap off the pawl/damage the ring or perhaps damage the selector system etc..Both cars have good drum type handbrakes so they are more than capable of keeping the car stationary in neutral,parking on a slope I sometimes use 'Park' if there is no kerb to point a wheel at .

Always makes me wince when watching old American TV programs, where big American cars lurch to a stop, then rock forwards or backwards against the gearbox parking pawl, as the driver gets out. They just slam the gearbox into park and never bother with the parking brake. I just think of all that strain and wear on the driveshaft joints

The handbrake is also the emergency brake, so handy to have it operational and not seized up should you ever need it for real !

I do try to keep our cars reasonably 'serviceable',anybody doubting the corrosive abilities of driving and parking in 'sunny' scotland might be interested in a couple of pics taken last year.
I had realised that the Rear Brake Backing Plates had corroded severely on our 2008 Sportage - so I replaced everything on both sides.
I also replaced the handbrake cable on one side since it was totally seized up internally (water ingress caused by split rubber boot).

The first picture is after removal and after only very light hand pressure on them LOL


Brand new genuine Kia Back Plate straight out of box...


Job almost complete - there is an axle stand under the car btw and there had been a strong block of wood under the arm of the trolley jack whilst working on the brake unit

When I was in high school, I got a flat tire when driving my motherís car.

Everything seemed fine until I went to get the spare tire.

It relied on four bolts. The flat tire had five bolts. I was clever enough to realize that this was not going to work.

The dealer that sold us the car bent over backward to find a suitable replacement.

Hardly anyone in North America would think of doing anything else. It's marked P for "Park" for a reason.

In many cars and trucks I've driven, the parking brake is operated by a foot-pedal labelled "Emergency Brake". In more modern vehicles, it's now operated electronically and you need a YouTube video to show you how to operate it!

A couple of years ago I needed a simple stopwatch for motorsport use. I found a cheap digital one. Itís the most complicated timepiece Iíve ever owned. It has three buttons rather than the one I was used to. If the wrong button is pressed you need the instruction sheet to get it back to where it was. Because of this Iíd put in away in my desk and never used it. I recently cleared the drawer out and finding it there I pressed a button to see if it still worked. It did. Unfortunately Iíd inadvertently set an alarm which meant it seemed to go off at random intervals and Iíd mislaid the instruction sheet. The damned thing annoyed me for over a week until I finally worked out how to switch it off!

I kept hearing something softly but irritatingly beeping three times in my house. It seemed to come from the front room but never when I was in there. Hunted through a small chest of drawers, no luck. Worked out the interval between beeps and made sure I was in there - really hard to pin down exactly where it was. Definitely the chest of drawers. Pulled everything out. Eventually realised it was a CO2 detector which was amongst a bunch of stuff I'd "inherited" from my mum's flat when she died - I'd picked it up several times and dismissed it; it was letting me know the battery had all but croaked...

I'm sorry, but you actually let your cars get in this condition? I'm astounded....... An accident begging to happen.

Well past it’s best, but the badly rusted part was the dust shield for the disc. It’s not structural and not part of the brake.

Dear Astounded of Yakima

LOL - the Brake Back plate was actually still in one piece whilst on the car and looked in reasonable condition,it only fell apart during removal,the Back Plate is only there as a shield to keep road grit etc away from the main and parking brake components + ABS ring/sensor.I only found out how corroded it was when I was diagnosing/fault finding the poor handbrake performance on that side.
The car had recently passed its annual MOT test with no advisories about the back plates.
I tried to get it booked in to a local garage but they said Kia had nil stock and suggested just removing the back plates completely,I was not happy with that suggestion so spent the next couple of days sourcing the necessary parts to complete the job.
It may have escaped your notice but the Back Plate is completely hidden from view unless you remove the wheel and have a good shufti in there.
The road salt (white) they are now using up here is extremely corrosive,I think much more so than the old Brown Road Grit (which they still use in some locations),over the summer I am going to tidy up the underside and completely replace the front suspension and steering components.

My local train station now has lights and lock on the crossing gate - the lights go red and the gate locks three minutes before the train arrives... which then stops at the platform *before* passing the gate.

The upshot being that if you are not on the platform five minutes before the train is due to depart, you end up at a barrier watching your train arrive and depart without you.

We have a small railway station in our village. Same problem, if you’re on the wrong side of the road gates in good time you can’t get across the lines to the train. There used to be a footbridge within the station to cross over but that’s been gone for years. It was replaced by a pedestrian gate to the side of the road gates, but modern people aren’t clever enough to use it, so that’s been removed, too. Reverse progress.

You need to be at Lostwithiel station in good time for your train to avoid the same problem; no footbridge on the station. Was there on a Sunday a couple of months ago; made sure we were over the crossing in plenty of time as the next train was about two hours later (Covid disruption to the services) and the pubs weren't up to much - the one that was apparently best was shut! Crossing the other way earlier on we had to wait for trains in both directions so even if you are in ample time to catch your train, you still might get stuffed.

I bought a really cheap replacement DVD player because it was all region. It works okay, but the remote was designed by some committee that had never played a DVD. The most commonly used button is the play/pause button; where is it on this machine? Look at the second from bottom left button....... Brilliant user friendly design. I have no idea what most of those other buttons are for.

Looks to me like a generic TV/DVD player control. A combined control would be more focused on TV control as that is what would be used more frequently.

I'm guessing what you have there is more an example of cost cutting than poor design.

Why design and produce a bespoke remote control when you can buy one of the shelf and print your company name on the case?

Just being Devil's advocate, the most commonly used buttons are grouped together at the bottom - easiest to find and reach?

But I think you provided the real reason when you said you "bought a really cheap......". What did you expect, buying a 'toy' player instead of a real one. Cheap does not necessarily equal good. To make something cheap, many corners have to be cut, one of them probably being the design of the remote. Other corners cut will almost certainly be the error correction of the raw data from the disc and the signal processing of the final image and the audio.

Buy for quality not for price, or buy cheap, buy twice.

And if the train brakes failed and the crossing just beyond the platform was not secured shut..........?

I am surprised that some folk seem to expect to arrive less than 5 mins before their train departs - that is cutting it fine.

It works on the London tube system, because if you miss a train, you will only have to wait a few minutes for another.

But for a mainline, scheduled train, I would get there with plenty of time for traffic jams or problems on the way; to park, or be dropped off, buy my ticket, find and walk to the correct platform etc. I wouldn't arrive only a couple of minutes before departure. Any traffic or queues at the ticket machine etc would be a problem.
