I thought you got a lot for that 20% though:

Don't have to walk to wherever car is parked

Don't have to drive

Don't have to park car

Don't have to walk from parking spot to actual destination

Plus no risk of getting speeding/parking tickets, and if you are in an accident no insurance hassle to worry about (I assume the car sharing services have some sort of excess if you get into an accident).

Recently car2go added a $1/ride fee that was for insurance. If you reached 99 trips in a year, you didn't have to pay that fee (or similar).
