I have been away from Denmark for over 30 years, but before then, the tax laws allowed new rental cars to be purchased "tax free" as long as they earned money outside Denmark for at least 12 months. So, each year, the Danish rental car companies had a need to move hundreds of cars back to Denmark from around Europe. The companies would give us starving students a train ticket, gas money and something like 5 days to drive from Rome or Paris back to Copenhagen. My fondest memories was the partying on the train trip South. Needless to say, that we stayed in, say, Rome as long as possible, then drove home from there in record time. One year I remember driving a Benz back from Rome. There were no "electronically limited top speed" back then. What a blast through Germany on the Autobahn. Remember, we HAD to go fast because we had partied and stayed in Rome too long... I think that was the year my buddy didn't make it back in time. He was jailed in Rome -- they didn't like his "backstroke swimming" in one of the fountains at 4am(!) Man - to be young and foolish again...
Sorry for the long story, but that "no tax on taxis post" brought back memories...

 

90% of Taxis in Copenhagen are diesel Mercedes Benz. As a starving student in the '70s I drove one on the weekends in Copenhagen. I remember one American couple getting in my cab and giving me a destination. I said "But that is only two blocks down the street" Her reply was "I know, Herb wanted to ride in a Benz just for the heck of it." I and drove them around town for 10 minutes and got a great tip!

 

thailand have a tax of over 200% of the car price... plus a lot of other taxes..

personally, i think its a political strategy to reduce the amount of cars here, because damn the traffic is insane on rush hours...
