Factual error: The street signs in Beverly Hills are green on traffic signals, not blue as shown in the film. Blue signs are in Los Angeles, where the movie was filmed.
Factual error: When Axel first drives from the airport (while on the phone) towards Beverly Hills, he is coming from the wrong direction. He is shown on the interchange from the 105 Freeway westbound to the northbound 110 Freeway heading towards Downtown LA. If coming from the airport to that same intersection, he would be on the 105 eastbound into the 110 - not westbound.
