  1. modern battery and electric motor technology have removed most of the inefficiencies in powertrains (gears/clitches/transmission tunnels/transfer cases) and optimized almost evrey aspect. when you look at a model s plaid powertrain seems to have been tuned to provide exactly the maximum torque that can be transfered to the wheels when accelerating, with 33% front/66% back maximising grip during the strong weight transfer happenning from 0-60mph. past 60mph its pretty much flat power curve that maximises the power that can be delivered by the batttery, and handled by the motors/controllers. rpm/gearing optimized to achieves fastest top speed that can be safely handled by tires considering the weight, with a comfortable safety margin. Even if you tried to improve it , you would hardly be able to do better. in drag racing, more torque/power and very sticky tires would help, but on a track, more power would get very minimal gains by overheating the battery, and tires, on the road under speed limits more power would be cut by traction controls. Now almost who's ready to spend a bit more for performance can have access to a family car with massive amount of power in a reliable and cheap to operate daily driver car (model 3/Y performance, ioniq N, EV6 GT, Mach E GT, upcoming volvo EX30...) We are slowly getting to point (or already at the point) where most people can have way more power that they can/want to use. I think the next big thing in cars will be (active) suspension technology..."active" suspensions with different presets for damping and ride height is just beginning and 1/10 of the equation. truly active/predictive suspensions with cameras/radars that soak up every imperfection, corner perfectly flat or even lean into the corners( think bose suspension), maintain perfect wheel geometry and tire contact patch throughout corners (new 992 GT2 RS active camber), and gives you better grip and better comfort over any road and at any speed, its potentially the ride comfort superior to luxury car, and handling/cornering similar to the best sports cars. Even if theres a weight penalty, the potential real life benefits way overcome the weight penalty I would happily trade 10% acceleration for a suspensions that would completely cancel potholes and speed bumps, corner/accelerate/brake flat like a go kart. There's a problem though, it could lead to people losing sensation of speed and speeding in residential areas/cities, not slowing down for speed bumps, and progressively going faster and faster over speed bumps, potentially reaching a point where they go passed the limits of the system and losing control at very high speeds.

  2. some critics about the CT came from the cybertruck leaked reports that showed evidence of very bad braking/handling issues. we''ll have to judge on the final production version though
