Are you 2x as likely to become a paraplegic after a motor vehicle accident at 30mph as you are to die? That doesn't sound right.

> fewer people traveling

I don't think anyone says to themselves "it's a 20mph zone on the route so I'm not going, if it was 30 I would go." Lower speed limit != fewer travelers.

> less air population

Assuming you meant pollution, the same amount of cars going slower would cause more pollution in a given area, not less.

> people having more time to meditate

I'm sorry what? Most people don't meditate, and how is sitting in the car longer going to give you more time to meditate?

> Lower speed limit != fewer travelers

Longer travel times result in fewer people wanting to travel. Was not expecting this to be controversial.

> The same amount of cars going slower would cause more pollution in a given area

Drag is proportional to the square of the velocity

> Most people don't meditate, and how is sitting in the car longer going to give you more time to meditate?

Meditate is perhaps the wrong word.

In general the slower you drive the lower your mpg (and hence pollution).
