Because we don’t need to increase performance, if we think if performance as horse powers and speed. Cars are fast enough, even too fast for private vehicles.
Living in Germany it is quite ridiculous that we don’t have speed limits on certain parts of the Autobahn, nobody needs to drive 200 km/h. You won’t get faster from A to B, it’s dangerous, it’s stressful, you need more energy. If you want to race, go on a race track. I assume it even costs us more to maintain roads so that you are able to drive more than 140 km/h.
