These are great improvements and I'm sure will benefit the serious taximen and of course customers. I just wish they'd mandate a standard colour for taxis as well. In Germany the tendency is now towards all over vinyl taxis, which means a well maintained taxi can still be sold on after it's too old to be used as a taxi and the buyer doesn't have to drive around in an 'ex taxi', so to speak.
See a video of the vinyl being removed here. The vinyl also protects the original paint and keeps it in almost new condition! I saw a documentary about it recently. It is also considerably cheaper than a respray and even private customers in germany can get a new car look by simply changing the colour of their car in this way.
