I used to do that on my Honda C90 - I could approach someone in the slipstream at a little under 60mph but there was no way I could get past them.

I'm only going to be sitting alongside someone if they've increased their speed whilst I'm in the middle of overtaking them. I'm not going to break the speed limit to get past, and I'm not going to drop behind - why on earth should I?

For a speedo control yes, use satnav and set 50. By and large you will be in a slug with most vehicles in one lane and slower in the other.

GTW, the average speed cams I was thinking of are on ordinary roads where the road twists and turns and the Spec speed can't be maintained through out though you could, if so inclined, achieve a higher average.

Oh yes - the slipstreaming effect pulls you along, throttle back a bit and save fuel. Only to be used by those of us who have quick reactions.

Unless in a convoy with a load of trustworty mates I now only use it briefly for a bit of extra last-second speed when coming up to overtake a slower vehicle.

Used to have fun in pre-speed limit days with F Type's Sunbeam Stiletto (warmed up Hillman Imp). Catch up with a Jaguar or similar doing 90ish, with precious little chance of overtaking, but would keep pulling out in dummy overtakes, each one apparently only aborted by oncoming traffic appearing. Pretty soon, the Jaguar passenger would turn round for a good look, presumably in response to the driver saying "What the **** is that little car behind that keeps trying to overtake us?"
Our children really enjoyed it, and I got quite good at dividing by 0.875 in reply to their question "How much bigger is their engine than ours?"
Our children have now grown up and left home, but I haven't.

I had an old Hillman Imp. It had the usual problem of the head warping and breathing coolant. As the heater was up front this would stop working through lack of hot water and mine, being to old to have the bleeding valve by the heater, meant that I had to go through the performance of slackening off the hose, let the air out, and tighten it up again.

Somebody dumped a rusted through Stiletto in the nearbye abandoned railway sidings and in no time I had the engine out plus a few other 'delux' bits. My cylinders were in a better shape but I used the head, manifold and carburettors. This cured the heater and put lots of oomph into the car generally.

The beauty was in winter. Like the rear-engined Volkswagen it was magic in snow. Snow clearance was non-existence on our estate and the number of times I would pull neighbours cars up to Mercs and Beemers out of the gutter were uncountable. The ultimate came when I bought a property at the end of a long uphill road.

With six inches of snow I would stop at the bottom. The kids, 9 and 7, would sit on the engine cover holding on to the window struts through the open rear window. This would put max weight on the rear tyres and the car would scoot up the steep hill without faltering. At the top the depth would increase to a foot but the front would then ride up and having a flat bottom it would surf over the snow steering with the front wheels.

Never failed to get up.

I swapped a Jaguar MkII 3.4 for a Hillman Imp - the Jag was drinking oil (and petrol) and I was supposed to be saving to get married.

I swapped the Imp's 12 inch wheels for 13 inch wide rims with low-profile tyres, but had the usual exhaust valves and water pump problems - oh and a transaxle failure (casing split), so I ended up spending as much on running the Imp as I had on the Jag.

I learned to drive on the road in an Imp (actually the slightly posher version, The Singer Chamois).

FED,
In the winter, living up in the snowy Peak District hills we would do exactly what you just described. We got extra wheel traction by threading rope through the holes in the rear wheel faces and across the tyre tread. That car would go anywhere in the snow, as long as you didn't ground it. One of us would drive and a couple more would sit on the engine cover, holding on through the open rear windscreen which allowed you the option of quickly jumping off to push.

Ah yes, the good old Imp. I had a few of those in my university years and after. I tried all of the varients but the best I had was also the cheapest. I bought the Stiletto for just 30 in 1980 as a low mileage MOT failure. It had started rotting through the sills and floorpan in a big way but it was about all I could afford to buy while trying to live on my student grant. My father borrowed some gas welding gear and we rolled the car onto it's roof on the front lawn and spent a pleasent afternoon welding the floor back in. When done we slapped a load of paint on, with a brush, then rolled it back up the right way. It was not pretty. We refitted the battery, put water, brake fluid and engine oil back in and fired it up. Sweet. A week later I was MOT'ed, insured and back to Uni in it. There was a strange smell of tar/pitch in the car as the welding had melted the pitch the makers had used to fill in the stiffening corrugations in the floorpan and it had dripped and solidified on the headlining, the underside of the dash, the underside of the seats and anyware else it could fall when the car was upturned. I was uncatchable in it. I had worked up from the lowest powered version of the car and had become accustomed to keeping the speed and momentum up whenever possible, don't slow down for bends if you think you can get around them as you are. Everytime you brake you waste energy and it takes time (quite a lot of) and fuel to get it back. By the time I got into the Stiletto I had conservation of momentum down to a fine art and that, coupled with a bit more performance, used to get me about faster than many a more powerful car driver expected. You could feel their frustration at times when they couldn't lose me on the twisty stuff. I ran that car for 4 years but eventually got fed up with spending so much time under it to keep it going that I sold it on. Happy days.

Rans6Andrew, it is a shame that modern drivers don't use momentum. There they are, doddering along at 40 on a winding B road with a 60 limit, great fuel economy THEN the road disappears around a gentle bend BRAKE, or a car appears coming the other way BRAKE.

I can absorb one bend then the gap is gone and unless I join their stop-go I need to accelerate to 60 before settling back to a gentle 50-45, or stop for a nap.

Sunbeam Stiletto available but no blanket speed limit? What year was this?

I never had an Imp, but knew plenty people who did.

I consider myself fortunate!

Used to cause much amusement watching Imps racing at Siverstone in the 70's as they came through Becketts on three wheels !

We occasionally rolled Triumph Heralds on their sides on to old mattresses to do inspections and repair the chassis if necessary - much easier than being on yer back underneath!

You see this a lot at night, soon as a car comes the other way they brake. I reckon it's a sign of poor eyesight and if so question whether they should be driving at all.
Braking costs money, you are effectively converting expensive petrol into heat, so avoiding it saves money. Anticipation is to me the most important and vital skill in driving, it keeps you safe and saves money. Overtaking a car and then braking behind the next one in a queue of 8, thus gaining nothing, is possibly the most pointless manoeuvre in driving, for example.

You can see a lot further ahead on an empty road with full beam headlights than you can on dipped lights with someone else's headlights shining straight in your face.


If you follow the usual rule, that you must always be able to stop in half the distance you can see to be clear, then if you can't see so far you can't go so fast, therefore you have to slow down. Basically just physics.

GTW, they lit up the road for you. On a right hand bend I keep illuminating the while the other car comes around then I dip.

Andy, in my youth a line of 8 at 30 mph was no problem when I had 30 overtake, did have to make an emergency diversion in to a layby on the right once

Only in front of them. You're taking a bit of a gamble that you don't hit an unlit cyclist or parked car the moment they've passed you - no ta.
