Re: Electricity vs Petrol/Diesel prices
"(max allowed in the US is 11 hours driving, so can go into 6-800km a day for a long haul trip)"
Actually it is more like 11 hours driving at 100 kph - 1,100 km.
Long haul trucks tend to carry fuel intended to keep them rolling for a day's work... and many interstates have a speed limit of 65 mph = 105 kph, and I have often seen big rigs rolling at 125 kph or more, in 'convoys', not quite nose to tail.
