Better idea...double-deck the 405 parking-lot..err..freeway
Another freakin' HOV lane. Big help. Luckily I don't have to drive on the freeways these days, but if I did, I'd probably do what KFI (AM640, Los Angeles) host John Kobylt does: drive in the HOV lane even when I'm alone. Take the occasional ticket as the cost of getting home 45 minutes sooner.
