Congratulations, Proterra, you are officially the biggest vehicle I’ve had in front of my camera! I’ve had some pretty wild machines that climb mountains with fury, sophisticated yet rugged vans, priceless pieces of metal, and winner’s circle racers… but this one takes the cake for sheer size. Oh wait, this huge bus gets 600 miles per charge?!?.. which translates to 350 miles of continuous real world bus driving transporting actual people?!?.. which basically means city streets are about to be humming with these clean and quiet machines.…
