I couldn’t see this being a viable option in my work, I drive a Scania R450 pulling a tri axle trailer on multi drop from my base in Plymouth throughout hilly Cornwall, most days fully freighted and heavy. When I get back to base late afternoon a night trunk driver is waiting to take over, and after a 10 minute refuel it’s back up the road to the Midlands to bring down our frieght for next day when I take over again.
The wheels barely stop turning, so unless this Tesla device can be fully recharged in 10 minutes or the regenerative charging is a revaluation I can see only a very limited (excuse the pun) scope, possibly with supermarket fleets.
