in which country can you actually drive?

so as some heard my country (germany) is planning to finally legalise. most people are happy, i am not. i love driving and they have nothing planned on that it seems. i googled about the netherlands and apparently you cant really drive there either, if you are someone who smokes regularly. same thing for california it seems?

so i was wondering, where can you smoke weed and still be legally using the car? i dont mean like getting fucked up and then driving slower than a bicycle just to get some fast food, but getting to and from work sober and then ripping that bong until you go to sleep.
