We asked, and you answered! Here are the results from last week's poll questions.

In New York City, the mayor is calling for a group of taxis to be all hybrid cars. Do you think this is a good idea for most cities?

Yes - Hybrid cars lower CO2 emissions - 60 %
No - It would be too expensive to replace old taxis - 21 %
Maybe - Speak out! - 17%

Speak out about this week's question!

Hybrid taxis are a great idea. My family has a Hybrid car and we really like it.

Yes. I think they should use hybrid cars because they are great and even if it would be expensive to replace them it's also expensive to buy gas for them and when you have a hybrid car you don't need to spend so much money on gas.
Ashley, 13, United States

No, because it will get pretty crowded and a car accident can happen pretty easily.
Alyssa, 9, Canada

I say no. Hybrid taxis may cost the city too much, and cities need to spend their money on other things.
Clive, 10, United Kingdom

I vote maybe. Some cities might not be able to afford new hybrid taxis.
