I drive a hybrid and a conventional ICE with automatic engine restart.Yep, agreed. There are loads of alternatives to leaving engine ticking over.. But taking grand kids to school it's amazing how many cars you see parked up with engine running. I don't get that at all this time of year, it's not for heater or air con. Just folk trying to be annoying I suspect.
The automatic restart works acceptably in long stop start. But has a horrible tendency to stop as I am waiting at a white line for a gap in traffic. Just when you don't want it to. Therefore I often switch it off which defeats the point of having it in the first place. And results in what you see outside schools.
Whereas the hybrid behaves impeccably. Easy start on electricity only. When I am driving and partner is left in car for a few minutes outside a shop, I often leave ignition on. Mostly engine does nothing but she can still keep warm/cool, operate windows, etc.
