Is it time for car companies to take 4x4s out of their car ranges?

It's not a big deal. Industry does far more polluting than people in 4x4s. The government should focus on important issues.

Yes, they serve no purpose for families travelling on smooth tarmac roads. They should only really be used by farmers and people who need an off road vehicle.

Its people's individual decision, no more than that. 4x4s may pollute more than other cars, but in the end it's a person's decision, nothing more.
