I've had a few 900 mile days in my time but that's a rarity. The problem with electric trucks is they don't fit with how the industry runs currently. Yea I know change the entire industry to fit the truck right?
In a perfect eutopia drivers would show up to a shipper on schedule with a trailer that's clean and prepped ready for loading and the shipper would have the load waiting on the dock ready to load. 10-30 minutes later the truck would be ready to roll paperwork in hand.
In the real world the driver might show up ready to go at the appointment time but the load isn't ready for another 3 hours. The load may be ready but the driver is 3 hours late and the trailer is a mess and needs washing before loading. If the driver is on time and the load is ready odds are the system will crash and they'll be waiting on paperwork for 3 hours. Any way you look at it the whole system is against timely delivery and loading it's why we are allowed to drive 11 hours a day, we are usually lucky to get 8 hours of actual driving in due to negligence or just bad luck on someone else's behalf.
