&gt; That neglects the fact, that most of the maintenance costs are not engine related.<p>It probably doesn&#x27;t. Already today operators of taxi and bus fleets are doing the sums on full electric vehicles and deciding to spend more up front to save over the long term. Generally lower fuel and maintenance costs are cited as why they can afford to spend more on the vehicle. Possibly these multi-million dollar deals are signed without sufficient due-diligince by people who run vehicle fleets as a full-time job, but it seem more likely they know what they&#x27;re doing.
