I know this sounds a bit funny, but if you have a car you are LUCKY. Thank Hashem for that. We don't have a car anymore and it's been a major pain in the arse. One day when I have a car I'm going to give rides to as many people as possible. With great power comes great responsibility and we should use all of Hashem's gifts to us for the greater good of helping others. So next time your friend needs a lift, you see somebody in need, or you're able to help somebody out with a ride, you should do it.
