What if the nearest charger is out of your way, and you aren't trying to go home? Is it better to be towed 15 minutes out of your way and then charge up for 20 minutes and then drive another 15 minutes to get back to where you were, or just get charged up for 20 minutes where you are? They could even combine the two, get towed on your current route while being charged. Frankly if you run out of charge you probably don't even need a full charge, so this truck could probably get you on your way in 5-10 minutes. Much like instead of being towed a few gallons of gas could get you moving again in an ICE.
