Google's wireless broadband team has a new target market: NASCAR racecars. The company is seeking permission from the FCC for an experimental radio license to test "the transmission of broadband data from racecars to transportable/fixed base stations located at racetrack facilities." It's all happening this summer at four events in NASCAR-crazy Tennessee, Michigan, South Carolina, and Virginia. The application, filed with the FCC on Friday, is highly redacted and provides only limited details about the plans.
