I mean, sometimes industries are dumb, and there are certainly people driving oversized vehicles on the road right now, but if you can find places to optimize vehicle weight outside of the engine/transmission/fuel you're replacing with batteries/motors, that applies to regular old semi-trucks; if you can make a semi-truck weigh 5000 lbs less without compromising on its design parameters, you can make every other semi-truck on the road more fuel efficient and save like 6% of your fuel costs, while also allowing you to haul bigger loads than competitors' trucks. Everyone making semi-trucks is interested in that, not just Tesla.
