Waking up on the way in, de-compressing on the way home. Exercise is built into my daily routine, and it "costs" me half the time I exercise because driving the car would take up the other half. And this time of year listening to the birds, especially the last 3/4 mile, is just icing on the cake.
And convenient parking. SUV and pickup drivers fight over parking around my office, some of them end up over a quarter mile away, and I just roll up to 50' from the front door.
