(that is why the truckers sleep with A/C or heaters on and engines running at rest stops) The Electric Vehicle motor has none of these problems.
In general, the time lost and extra energy for idling are the INCREASED costs of traffic jams that are increasing due to the lack of additional LANES, which appear to be held up by a lack of transportation funding. And the population growth is greater than the growth of road maintenance money. The US is being penny-wise and dollar-foolish!

Do cars even idle anymore? The last couple of cars we rented while traveling shut off when you came to a stop, kinda like a golf cart.
