Huh, I didn't interpret stalling while idling at a stop as a danger to others on the road. Especially when the car can be started again. The same principle applies if I accidently stall my manual vehicle.
To play devil's advocate it can be an issue if you're stalled out long enough that cars start moving around you on narrow roadways with oncoming traffic, but in my case that was completely mitigated by choosing the route and time carefully. Wide, empty roads are ideal.
