Winter is still a problem for EV. My city (non US) tried to change all busses from diesel to electric. Diesel busses had an efficiency of about 98% (2% time spend in maintenance) while EV busses had about 94%. This ultimately resulted in transport companies to go diesel again in recent years. I think putting some public funds here would be very worth the gain. Of course electric busses are vastly more convenient. They are almost silent compared to the heavy noise a diesel bus makes on acceleration. Their routes are predictable, so charging can be accounted for. Although a bus can also mount very large batteries to begin with. But apart from the slight difference in maintenance quota, there also was a problem in winter. When it was cold outside many busses refused to work. They would need to stay within a depot in winter which increases costs again. Still electric busses seem to be an efficient way to curb in-city emissions and noise pollution to a large degree. And I think the problem with temperature can surely be solved somehow. I do think perfect became the enemy of good here. But there are still valid economic reasons for the private companies that provide these vehicles. Ultimately they don't get paid for their vehicles to be more economical and less noisy. I don't think it is worth to replace heavy machinery yet. There are just too few vehicles that the investment doesn't seem too reasonable yet as long as there are that many more efficient things to replace.
