I do both, it's mostly a matter of what kind of ride it is. Mon./Wed./Fri. I commute to work and back so, of course, I start from home.
Tues./Thur. we have club rides in the evening (6:00PM start) so I drive to work in Los Angeles, drive from LA to Irvine, do the ride, usually go out to eat with other riders after the ride, then drive home. I really enjoy the rides and the people, which is the only way to justify 85 mi. of driving for a 35 mile ride.
Then on the weekends I usually do big rides in the mountains, so about a 45 min. drive to Encanto Park in Duarte or Glendora or Red Box or where ever the ride is originating.
Sunday is recovery day so sometimes fixed gear from home, other times club rides; so Sundays vary a lot. Since I'd driven to rides on Sat. and Sun. for Memorial Day (Mon.) I did a ride from home with my wife and a friend.

Thankfully we have some good climbs very close to our home in Whittier. Our friend took a photo of my wife and me at the Starbucks in Uptown Whittier:
We are very fortunate to have lots of good places to ride, either right out the door or within a reasonable driving distance.
