Delhi Transport Minister Gopal Rai said the odd-even formula will be reviewed after 15 days.
The Delhi government on Friday said Delhiites are not so "negligent" that they will buy extra cars to beat the odd-even formula even as NGT expressed such apprehensions.
The National Green Tribunal cast doubts over restrictions on private vehicles under the Arvind Kejriwal government's odd-even formula, saying that it may may even encourage people to buy two cars.
"You can live without food and shelter, but you need to breath even when you are sleeping. I think Delhiites are not so negligent that they will do it (buy extra car)," Delhi Transport Minister Gopal Rai said.
He said the odd-even formula will be reviewed after 15 days and the government will come up with ways to reign in those buying extra cars to beat the scheme.
The green panel's observations came against the backdrop of a volley of questions being raised including on security concerns for women and adequate public transport to deal with the situation.
"The odd-even scheme which you are proposing to implement what consequences is it going to have on traffic and pollution? What will be other measures which you propose to set up to make your plan a success. In our view this may not serve the ends which you are trying to achieve," it said.
