We dropped our 2nd car in 2014, I exclusively commute by bike now. DW still drives a 3dr VW UP to get to work, she has a disability so can't go without unless we lived in the city centre, but with a dog and kids on the way, it wouldn't be ideal.
I nearly never use the car, aside from the rare visit to Costco (think 20kg sacks of rice, 12kg sacks of flour, 25kg sugar, 3kg of coffee. x64 tins of beans x64 tins of chopped tomoatoes sacks of onions, potatoes, etc
All this keeps my weekly shopping trips down to just buying perishables and saves a shoot tonne of money to boot. Food shopping is easily done on the bike when the heavy lifting is left to the motor. Also get used to not buying liquids like Coke or fruit juices, they are rubbish for you and very heavy! I don't mind a special trip to the supermarket for some ale from time to time, though sticking with obtaining it without a car helps me cut down.
