Gasoline on Clear Coat
BMW (like most high-end European auto manufacturers) uses a polyurethane-based clear coating on their cars. This coating has functional additives that makes it resistant to MOST contaminants that can end up on the body. This includes gasoline. BMW (as opposed to DC, Audi, VW, Volvo, Porsche) uses a powder-based clear coating. This coating is applied to the pigment coated body as a slurry and is then baked on the car at 140 degrees C. The other guys use a liquid clear coat that is also baked on. The baking process is actually a molecular cross-linking (curing) process. It makes the coating tougher (more scratch resistant) than "normal" polyurethane. There are functional additives that increase the resistance of the coating to UV, salt spray, acifd rain, and gasoline (and other solvents).
Hence, there's no need to be concerned about gasoline exposure. As well, the marketing guys at these companies worry about things like gasoline spilling from the fill spout of the car.
Similar activity for the tires and wheels.
So, no need to worry about the coating and gasoline.
