Right after Tully obtains the charger the shot changes and he is back in the truck.
The game begins in southern Florida. However it is quite obvious that the highway scenes are not southern Florida. The scenery (mountains, desert conditions) have the characteristics of southeast California.
When leaving the hotel in Key West to start the race, there are several high rise buildings in the background. However, there is exactly one 'tall building' (6 stories) on the island, and it is in the center of town.
In the opening sequence, the racers are going north on US1 from Key West. This road never has two lanes going in each direction surrounded by hills and bridges. It is currently almost entirely one lane each direction, with speed limits at 45 and many stoplights. It is not a freeway.
Driving up I-95 in Florida, supposedly going to Boca Raton, you see a mountain in the background. There are no mountains in South Florida.
