However, there should be NO exemption for the 1971 Chevy Rustbucket with no muffler, which burns more oil than gas, chugging down the road leaving a cloud behind it so thick it's a freakin' road hazard in and of itself. A car polluting like this needs to be required to be destroyed or repaired. Sorry your ox is being gored on this one, but your love of historic vehicles can't disguise the fact there are cars on the road which shouldn't be.
That's right, take the 80 year old geezer's beat up 71 Chevy away from him today and next you'll be demanding that 85 year old geezers don't have a right to wobble their 50 year old Schwinns down the road; when he's reduced to walking, make it a crime for anyone to use the right-of-way who can't make a pace of 5 FPS walking with his cane waving back and forth for balance.
Who are you to decide whether or not my 'classic' is worthy of a life ? If you want to throw sh!t at others, be ready for me to find fault with your ride...
