During Dr. Leland's court appearance for her speeding violation, Lester mentions she was driving a 3-series with the N54 twin-turbo inline 6 (engine). This is an actual BMW car and engine combination, and the internal company code used to identify this particular engine really is "N54." This means that despite his simple nature, Lester is a car aficionado and likely very tech savvy for even knowing this information.
This is remake of the 1991 movie "Doc Hollywood" staring Michael J. Fox.
She was arrested for having 23 unpaid parking tickets. Parking tickets apply to a vehicle and not a driver. Unpaid parking tickets would result in her not being able to register the vehicle.
