electrification is needed but it's often done the wrong way. instead of mandating diesel truck they should start by a electrifying all the shirt range trucks and passenger vehicles that can charge overnight and drive all day on a charge, with zero need for expensive infrastructures like super high speed DC chargers. just good old proven tech and batteries kept within 20-80% and charged level 2 overnight will last forever. level 1-2 chargers cnn be mass produced for very cheap. they don't even convert AC to DC or convert voltage, electricity just passes through. . public/school busses, dump trucks, delivery vans etc. they all do a lot of driving at low speed, in urban or residential areas, with a lot of stop signs , stop and go etc.these are the low hanging fruits that generates the most emissions, particles where the most people live.
