@jdoe @JetlagJen @nathans Yeah, that's another thing.

I rented a car which, unknown to me and untrained by the hire company, had a "lane assist" feature which wrenched the steering wheel out of my hands without warning.

I parked up and read through the hundreds of pages of manual and eventually found out how to turn it off. But the ****ing thing turned itself on again each time I started the car, and there was no way to stop that happening!

I reckon that a potentially lethal buggy feature like this should be defaulted off, and you should only have to read the hundreds of pages if you want to find out how to turn it *on*.

When I took the car back the guy at the hire shop said "yeah, it does that, it's a pain, isn't it". At least I know what not to buy now when my own car needs replacing.
