How many times have you "pre flighted" your car?
If my car was older than I am with said technology like most of the aeroplanes out there most of us regularly hire, then I would definitely pre-flight my car every time its used!!
If however the technology in the aeroplane was even half as up to date as my current vehicle I guess the concept of "jump in and fly" would be possible too.....
....just a thought, but then its been discussed before...
