As per Tesla Motors today:

"No more parking tickets for Model S owners. Today we’re introducing: ticket-avoidance-mode. Watch how it works."

The new system automatically detects "the presence of a meter maid or law enforcement officers" and deploys "counter-measures" to deter the ticket writer - from activating the windshield wipers to autonomously driving around the block under the "threat" has subsided.

+1 to Tesla today

Hat tip to Josh B!
