Another thing is that battery-electric vehicles can be used as drop-in replacements on all existing routes. You don’t need to do environmental reviews or meet with NIMBY stakeholders or shut down local businesses while you install the overhead infrastructure, you just buy the trucks and go (can charge overnight using on-board charger and existing electrical infrastructure… can expand this to accommodate the increased load like you would for any other increased electrical load like the move to air conditioning… but you can get up and operating immediately).
