White and Red are multi-coats so they cost more. White is free probably because there are less errors in the paint shop and more people would want it then black but that's just my speculation.
The Atlis XT has advertised this (perhaps a better version) years before the lightning was announced, if it's ever going to release is another thing...
I haven't really seen a video of people struggling with the yoke a week or two after they've gotten their S so I can't say I would hate it. Off-roading would be the least of my concerns with a yoke anyways, it's more city driving and people seem to be getting a hang of that quite well.
There would be no reason to add different trims just offer optional tires like they already do. But for other possible options there is the CT Quad, a trailer which hasn't been confirmed yet and the camping option which has been confirmed.
The CT might not have a 12v battery. Tesla is (or was) hoping to introduce their flex circuit to the Model Y in Berlin. This circuit brings down around 90% of the wiring and has no need for a 12v system.
I believe that Tesla will probably(>30%) have another CT event with the updated design.
While the livestream wasn't the worst thing in the world, there is so much more information about the truck that we don't know including what's new and old(there were rumors that the event ended way too soon...
EM said during q4(?) ir call that they would would lucky to get a few out to people by end of year. They will probably start production but won't deliver, at least not to regular consumers.
