8:30? Almost everybody is going to be walking to their offices at that time!
I would not recommend driving in the busiest periods, but nothing beats driving when it's quiet. You can get across London in fantastically quick times in enormously more comfortable conditions than the tube. I can be dry, have a heated seat, controlled climate, nobody sneezing on me, Radio 4 etc.

I'm guessing it's the usual, experiences vary but there is no way I would drive in london (or take a bus...)
