I bet you could go Calabasas to LAX in an hour - including traffic. And you could park for free. And that isn't being particularly aggressive or insane - just basic motoring between lanes.
If you DO need to get aggressive, I've made it from Long Beach to Santa Monica (near the beach too) in 38 minutes. In morning crush traffic
That was being hella crazy though, and I'll never do it again.
Bikes rule! I love the 944, but I hate sitting in traffic. . . If you want to dis the crush, get the bike!
