What about using WLAN technology here? WLAN uses the ISM band (microwave at
2.4Ghz) and will give you a range of several hundered meters
(outdoors). You will need long range so you have time to do a link
connection and data transfers before the car is gone (again). In a lot of
contries you can use the ISM band as you which as long as you limit the
power to some level. Check out:
