> So long as you monitor your battery charge you know the vehicle will get there

ahem, a BEV has __a lot__ more failure points than just "empty battery"...

sending a complex machine down a tube will _always_ carry the risk of the complex machine reading down. pneumatic tube "vehicles" are simple, they can not break down.

I am not an expert, I don't know which one is better or more reliable, but your claim that once you monitor battery charge, everything is hunky dory is wrong.
