With plenty of trucks fuming exhaust all over in any way they like + bunch ancient cars clogging the traffic and poisoning an air in front of your nose while being exempted - this begs the question: why shouldn't drivers of a cleaner cars get a tax break for being forced into submission to regulation but also being forced to breathe-in and smell the poisonous exhaust of exempt cars?

There are less problems with standards, more problems with double-standards.
