As most as money people died in the hurricane Rita evacuation as were killed by the hurricane itself. The reason is the freeways were stop and go and people simply began to run out of gas, increasing the gridlock as people abandoned their cars. Local gas stations quickly sold out.
However, EVs do not suffer a range penalty in stop and go traffic, and might even see a range increase over regular freeway driving. Had modern EVs been available then and if you had started the evacuation with an EV and full charge, most likely you could have driven the entire way to a safe distance on a single charge. If you did have to recharge somewhere and regular chargers were unavailable, you likely could have at least found a place to trickle charge.
In that instance anyway, an EV would have been the superior vehicle to have.
