Also I don't understand what does this have to do with climate change?
Traffic laws already limit how you are allowed to use your own car. This just prevents you from breaking the law. Your freedom ends where the freedom of another person to live a safe life begins.

Speeding cars make it a lot more difficult for other means of transport to share the road. In Europe many urban areas are limited to 30km/h (19mph). This allows sharing the street with bicycles, pedestrians and playing children. Speeding cars (speed limits are often seen as minimum speeds) make this impossible.
So the climate will come from people moving to other means of transport that are becoming viable and safe. Also public transport will be more attractive if taken a car takes longer. Europe tries to make its cities more live and loveable.
There is a difference between a part in the car to limit how you use your own Car, and a speed limit on the road.

This is an issue of enforcement, and its not being fixed because the EU is lazy.
Its as easy as installing speed traps and fines that hurt the drivers where it matters, the wallet.

The primary forces a car has to overcome are rolling resistance (proportional to the vehicles weight) and drag (proportional to speed). If you reduce the speed, you reduce the drag, and therefore you reduce the energy needed to maintain that speed (which decreases emissions directly in ICE vehicles, and indirectly in EV vehicles).
Automated speed cameras seem like a better solution than additional complexity within cars.
