Taxis needed ads to look decent?

I understand that taxi drivers could use a little extra revenue from advertising on their cabs but the other stuff quoted here by Andy Riga is just rubbish. Sticking ads on the roofs of taxis won’t “freshen up” or “rejuvenate” their image which wasn’t, in any case, in trouble, contrary to the ad sales guy’s claim. Taxis are what they are. So long as the car is clean – and, most particularly, that you can find one when you need one – it isn’t going to be improved by having an ad panel stuck on top.
