Where do you get your facts?  "Most are not long haul trucks..." Which of the innovative (agreed, not most) long haul fleets are moving to EV? Would be interested to know how the long haul truck fleets that have moved to EV are doing. 

Also, post office and courier often do much less than 200km a day?  I suspect that the drivers would refute that quite vehemently.  And all these vehicles sit idle overnight?

Just out of interest, what are your connections to these fleets?
