Yeah, two of my neighbors have Teslas. One a model Y and one a Model S. I've test driven one in Colorado and driven a couple locally. I get how they work. Point is - the software can't predict a future traffic jam. For
@JeffKeryk who never has to run the heat, or the AC, and doesn't drive across long bridges, sure, get just enough of a charge to get home. Pad it by a couple miles. Good to go.
But that doesn't work in the real world.
We, the Tesla owners and I, have talked about this exact scenario - the trapped on a bridge scenario - they do not run the car anywhere as close as the OP in this thread. They've been stuck in the same unexpected traffic jams that I have - things look good, and bam, you're on a road, with no exits, for an extra hour.
What good is re-routing you to a charger, if that charger is inaccessible because you're on a bridge? Or stuck in a tunnel?
The software may be good, but it cannot predict the future. People got trapped on 95, just north of here, for over 12 hours, in the ice storm, remember? How did the software do predicting that? And re-routing Tesla owners to chargers? They got stuck, ran the battery to zero by using the heat, and had to get towed.
Throw in a couple of long bridge/tunnels and it becomes a real threat. A daily threat.
I've been on the Chesapeake Bay bridge tunnel (17 miles long) when there was a crash. Three hours stuck in one spot. Nearest charger was on the shore, over ten miles away, and you cannot turn around on the bridge.
Power consumption when not moving, though, is not zero if, as I described, it's a day like today - over 90 degrees, over 90% humidity. You need electricity to run the AC. Or heat as those stuck on 95 found out.
Besides, your statement that such a scenario is not really possible is simply untrue.
It's not only possible, it is likely.
And Tesla owners around here account for that.
