Re: Tesla semi?
And that's a big assumption there.
Tesco does deliveries to supermarkets with its own trucks. OK, might be some leasing and other ownership elements, but they're in Tesco markings, They could run a fleet with solar-boost on the trailers. I don't know what they use in urban areas, these could be too big to be practical, and you might not get enough sunlight in England, but there are relatively short-range urban delivery runs.
And that sort of haulage operation could even swap from a long-range diesel to a Tesla for the urban leg. That does point to something Tesla may have missed. Low-speed urban maybe doesn't care so much about streamlining, but how well will this handle a standard trailer?
