The regulations are indeed shit. The conditions of the tests do not correspond to anything realistic.

Just look at the curve of the WLTP test on Wikipedia : https://en.m.wikipedia.org/wiki/Worldwide_Harmonised_Light_V...

Who drives like this? 1 minute to reach the high speed on the high speed test for example. The speed is never maintained, it's either accelerating or slowing down.

Today you see hybrids cars with tiny batteries that are close to useless just to meet regulations. In practice these hybrid cars smoke a lot, because it's cold and the battery is cold, because it's warm and you want AC, because you need to not drive too slow in the traffic, because the battery is already empty.

When the diesel gate happened, the French minister of the environment decided to test many cars on a track. They never published the results.
