it is a circuit and I have no idea how far would the station be from the vehicle during the race.
Do you think the wifi would work for a moving vehicle ? or do I have to switch to GSM?
You have no idea? You mean you know nothing about where this system is to be used? I suggest that is a place to begin your research. You need to know line of sight distances and elevations of the various circuits where it may be used.
Silverstone is only 2.2km across. Nurbugring is 2.5km. A base station in an elevated and fairly central location only needs a range to vehicles of about 2km to cover the whole site. That is viable for WiFi, LORA and even basic 433MHz radios could probably do it.
If you can't get the height to have line of sight various mesh networks could be used.
