It's the future of transportation.
The Arlington City Council got the chance recently to ride around in driverless cars, or "autonomous" vehicles which provide first-mile / last-mile trips to and from destinations, like the ballpark, stadium, theme park, etc.
The vehicles can top speeds at 25 MPH and hold 12 people.
Arlington's mayor is looking at the possibility of using the cars in the Entertainment District.
I'd ride in one of these if it meant not having to hoof it 2 miles to my car after a game!
