I don't have this feature, but I think I'll get it on my next car.

However, I sort of put this in the same category as a safety feature on a gun. Psychologically speaking, if you know all your guns don't have a safety feature, then you're definitely going to be much more careful at a subconscious level by default. There have been thousands of cases of accidental weapon discharges simply because someone thought the safety was on when it really wasn't.

Plus, if you have multiple guns or multiple cars, and some have the safety features and some don't, then that actually makes you less safe. In a split second, when heavily distracted, even the sharpest minds can easily get confused.
