NEW YORK - Size does matter, or at least it would under a new proposal unveiled by New York City Comptroller William Thompson, which aims at plugging the MTA's massive budget gap.

"We propose a new additional weight based transit assessment of $100 for vehicles weighing 2,300 pounds or less and nine cents for every pound over 2,300" Thompson said.

Currently New Yorkers register their cars for a flat vehicle tax of $30 every two years. Under the proposed plan, the tax would be based on weight.

A Toyota Yaris for example, a light and fuel efficient car, would cost an additional $100 to register while a Lincoln Navigator, one of the heaviest, would cost an additional $430.

"Everybody is going to have to pay more," explains Wiley Norvell, Communications Director for Transportation Alternatives. "Strap hangers are going to need to pay more and drivers are going to need to pay more to keep this thing going."

In addition to the new weight based fees, Thompson wants to resurrect the commuter tax which would add approximately $762,000,000 in annual revenue.

Altogether supporters say the proposals could generate more than $1.8 billion, enough to plug the current $1.2 billion budget gap.

But not everyone is on board, especially those who drive from the suburbs like Irene Bass of Jericho, who says she needs the bigger car to shuttle her kids.

"I think its horrible," she said. "Why would they do that? They have no right to do that."

Thompson says the weight based vehicle plan and the commuter tax could be combined with restricted parking zones in residential neighborhoods, where only New York City registered vehicles could park overnight.

All of these are simply proposals right now, but ones Thompson plans to present to the commission on MTA financing first thing Monday morning.
