I think the Rimac is cool and my peacock features are not drooping that it is faster.
I think it is amazing how close our favorite dog hauling family sedan is to the purpose-built, $2.7M, carbon fiber monocoque, yada yada sports car. I think it does guarantee that the Roadster will be completely off the hook.
I think we will see some sort of speed boost as Tesla gets more data on how the Plaids behave, maybe they will try to chase the 0-60 1.9s. I agree the Rimac will be well ahead of the Plaid, but I really want to see how the interim steps (60 ft, etc) break down. I think, one overlooked aspect of this is the SW engineering--at those speeds, the computers are doing most of the heavy lifting and some of it is going to come down to who has smarter algorithms.
One of the things I really liked was the performance controls and graphs in the SW for the Rimac -- hopefully that gives Tesla engineers some ideas on things they could add to our cars.
