Why car is a greatest invention than telephone?

See explanation for answer.

Explanation:

I personally beleive that the invention of the car is greater than the invention of the telephone because of the oppurtunities cars give us today. While both cars and telephones have evolved so much over the past several years cars give people the oppurtunity to commute faster to plces, and visit people and places. Whereas a phone may help you keep in contact electronically but can not get you anywhere physically. Then again as far as which invention is more beneficial overall I would say the telephone because it doesn't contribute to global warming like car gasoline does and has revolutionized the ways people keep in contact with each other. Anyways, I hope this helps!
