If you make the speed limit for cars 55mph people will still got a bit faster, 60mph, 65mph. But almost no one would be driving 85mph. But if you say "nah people drive 65mph anyway, let's be realistic and make the the speed limit" they will go 75mph and more. So if you want to not reach much more than 1.5°C, let's say 2°C or 2.5°C, you need to be realistic and set a lower goal. We will always be above any goal.
