Agreed. My guess is that this truck will go through a ton of "revisions" and that this is more a marketing stunt to take the wind out of Ford's Mach-E announcement.
The stunt will backfire if the cyber is significantly different that what was announced. They can't really change the styling, body, or glass to something less unusual without it being called out as a stunt. They could have done a stunt if they made less of a big deal, didn't let the media test drive, etc, but not now. If it were up to me, I'd would smooth out the edges a bit and give it a couple feet of flat top. It will still be unusual.
And there really isn't a need to change much, assuming it passes safety standard and comes close to the announced specs. Enough people are going to buy in on image alone for at least 3 years after production, and then they can go with a more traditional styled truck. Musk has said as much. Really, they don't even have to wait 5 years, there is enough room in the market for two styles of Tesla truck. People will buy the cyber truck based on performance and quirkiness alone, mostly from people who own a truck now or don't have much expectations from a truck...plenty of those.
The thing is growing on me a bit. I'm not going to buy it, but I have some respect for it now.
One thing that I think is incorrect is the statement that trucks haven't changed much in a 100 years. There have been some oddballs in there from time to time, but they've never lasted, or just were never really thought of as trucks. There's the baja outback, el camino's, avalanche, explorer sport trac, etc, all variations on truck beds. And everyone still goes back to the main overall truck design. Also worth noting that truck designs, and automobile designs in general, have always been limited by the need for an internal combustion engine.
