Avis has begun to offer a product called Autonet as an add-on to some car rentals, giving customers with a mobile device such as Treo or a laptop access to the net (and Internet radio stations, one assumes).

The service, called “AVIS Connect” allows customers to rent the router and service for $10.95/day, less than most hotels charge for daily WiFi access in a room. AVIS currently offers the service to rental car customers in San Francisco, San Jose and Los Angeles, with plans for service to seven additional cities expected soon. [RAIN]
