Tesla has plenty of resources. They have money to spare to hire any designers/engineers/developers in the world.
I love that Lucid are pushing them. We need more competition to improve the breed!
Tesla is still a fairly small company compared to the rest of the industry. Their resources are better than they were a few years ago, but they are still somewhat limited compared to other car companies. They are vastly more efficient at maximizing the effect of their limited resources, but there are still limits.
They are consistently profitable now, but that doesn't mean money is unlimited. They are still shoveling almost all the money after paying for operating costs and costs of production into R&D and expansion and only a small amount is left over for profit at the end of the quarter. I haven't looked lately, but a few years ago Tesla was throwing a higher percentage of its revenue at R&D than just about any other car company, but in total dollar terms it was one of the smallest investments in the industry. That's how small Tesla is compared to everyone else (other than specialty car companies than only make a handful of cars a year).
Expansion of development also is more complex than just throwing money at the problem. Having money helps, but things also take time to accomplish no matter how many people are working on it and how much money is thrown at it. One place I worked had a saying that it takes 9 months to get a baby, no matter how many women you throw at the job.
There are some things Tesla is doing that are so complex only a few people in the world may have the necessary skills. I saw an interview with the guy who is probably the top microprocessor designer in the world. I think he's had a hand in developing every major processor design in the last 20 years. Tesla hired him to develop the new autopilot processor. But if he didn't accept the job, there aren't many other options.
E-tron owners report the opposite. With a physical mirror moving the head will give different perspectives/coverage, but with a camera, the perspective is fixed until adjusted. Adjustment is not done on-the-fly though.
Also, dynamic range of our eyes are bigger and faster to adjust than any camera yet.
Added IR and radar etc can compensate for these shortcomings.
Good point. I was thinking about blind spot detection though.
