Look how they test the brakes (http://www.wired.com/autopia/2011/02/looking-inside-boeings-...):

>One of the final tests still on the agenda for the 747-8 test pilots is a maximum braking tests. The pilots will abort a take off at approximately 184 knots (212 mph) and come to a stop by standing on the brakes without using thrust reverse devices. The brakes must be at their maximum allowable wear at the time of the test. The brakes are 'pre-worn' a bit in the shop, but most of the work comes down to the pilots to get them ready for the big day. >"We do repeated, abusive landings to wear down the brakes," says test pilot Mark Feuerstein.

They slow down from over two hundred miles an hour by standing on the brakes.

Plenty of cars can do that.

Of course -- I don't think there's too many vehicle's on land with the momentum of a 747 at 320km/h. And definately not many that can compare on a momentum:surface friction ratio.
