I haaaaaaated the smell of diesel fumes when riding the school bus as a kid. And I still hate smelling it when dropping the kid off at the bus stop in the morning. Fleet vehicles like school busses are great candidates for electrification because they sit in one spot all night long, and have dedicated maintenance staff and long capital horizons. However given the shortages of lithium in the market, I do wonder if electrifying other vehicles would have been better from a carbon reduction perspective - buses are mass transit, and therefore already far more efficient per passenger-mile than a personal vehicle. Would electrifying a hundred PHEVs been better for the environment or fuel diversification? I won’t complain too much, though. We gotta electrify them all eventually, and thank goodness I (eventually) won’t have to smell diesel exhaust in my neighborhood anymore.
