I really dislike this at stoplights. It would be tolerable if there were a smart traffic grid and the cars could subscribe to get a notice at (45 seconds down to the multiple of shutdown interval duration div 2 and floored to seconds); of course if you did THAT street racing would use it as a starting line signal so it'll never happen.
Alternatively electrics only really turn all the way on when accelerating so something with at least an electric drive system is going to be the medium range solution.
- Tomte 8y agoWhy do you dislike it? The latency introduced by an „unnecessary stop“ is absolutely negligible. A second at most. Most people will regularly take longer to realize the traffic light has turned green.
- carry_bit 8y agoA second is huge when you're used to it being instantaneous.
- Tomte 8y agoAs it‘s only relevant a very small fraction of stops, but has clear benefits, I don‘t see the problem.
- sp332 8y agoAdding a second per car in line at a light is going to decrease the number of cars that can make it through quite a lot.
- greglindahl 8y agoThere are places with a lot of these cars already.
- dghughes 8y agoIf you're driving in stop and go traffic in a city in the winter when it's below freezing, especially -20C (-4F). Plus more than once I've had to watch my rear view mirror for someone about to slide into the back of my car. A second to get out of the way to too long in some situations. Sometimes just being able to quickly move 30cm is enough to prevent major damage and injury.
- Tomte 8y agoIn such extraordinary situations you can simply switch off the auto-off-on function. But that's a 1% kind of situation.
- poloniculmov 8y agoFrom my Ford Focus' manual: Note: The system only operates when the engine is warm and the outside temperature is between 0ºC (32ºF) and 30ºC (86ºF)
- blattimwind 8y agoThat's only a problem for automatic transmission cars.
- mmirate 8y agoMost people at the front of the queue of stopped cars, yes. The person 20 cars behind, who is threatening to waste several more minutes of my time if the two of us don't get through the green light? Unlikely.
- matt_the_bass 8y agoMy car has this automatic shut off. Honestly, the time it takes me to move my foot from brake to gas under normal driving conditions is all it takes to start the engine. For some reason this starting is WAY faster than the I Italia time the car on start. I’m guessing firmware loading more than engine starting reasons.
