Auto shut off cars

[jphanna]

We are told Over 90% of the wear in a motor happens at start up. Don’t know exactly the right percentage but its over 90% from memory. Now that is assuming it’s a cold motor in the morning when every drop of oil is in the sump.
If the motor could theoretically stay on after just one start, after thousands and thousand of miles, the wear would be negligible ….in theory.

Taxis with huge kms piling up, was evidence of that as they only start up and run constantly.

I have ridden to work for 27 years straight on a push bike. I sit at the lights and these days, hear a lot of cars with engine off and they start up as they take off. Usually, late model European cars, and late model Subaru seem to have this feature. I hear and see it every day now.

So 15 years from now, what are these cars going to be like as a high mileage second hand car? Will they have questionable motors due to constant stop (motor) start (motor) driving, and gone through multiple starter motors in that time?

One of those things that only time will tell.
