The track itself has undergone significant changes over the past two decades to meet  safety and other sanctioning bodies. Changes include the addition of the entire infield area in 1988 (present day turns   3, 4, and 5, eliminating the straight that started at present day turn 2 and ended at present day turn 5) extending the track from its original 1.9-mile (3.1 km) length to meet the minimum-track-length criteria of the FIM for MotoGP events, plus the more recent relocation of pedestrian bridges and embankments, and the expansion of gravel pits outside turns 1, 2, 5, 6, 8, 9, 10 for additional runoff. The original media center was demolished in 2006 to make way for additional run-off room in Turn 1. Also in 2006, the 'hump' at the top of the Rahal Straight was flattened to accommodate the MotoGP riders, though some claim that this increases the wind effects that can perturb a race motorcycle. Remnants of the old configuration can still be seen from the parking lot between turns two and five. They are found underneath a road leading to the parking area for entrant trailers and 

When not being used by the major events the track can be rented. Approximately twice a year the Sports Car Club of Americaholds regional club races for the San Francisco Region. Various clubs rent the track throughout the year for informal high performance driving schools that allow the public to drive their own cars at speed. The raceway has also played host to prototype testing of the Nissan GT-R in 2007.

The track is featured in video games such as the Gran Turismo series (including the bike version Tourist Trophy), Forza Motorsport, and the MotoGP series. In a bid to compare real life versus video games, Jeremy Clarkson of the British automotive show Top Gear attempted to beat his Gran Turismo time of 1:41.148 in a Honda NSX by racing the real track in the same car in 2005. During the trials, Clarkson determined that the game omitted a few details of the track, and the game's physics allowed him to brake later when coming into turns than he could in real life. As a consequence, reality prevailed and he managed a best time of only 1: However, both he and the track instructor agreed that it is possible to complete the course in 1:41 in a Honda NSX if the driver were sufficiently experienced, talented, and most importantly fearless.

It was also used in 1975 for the film Herbie Goes to Monte Carlo as a qualifying track.

Laguna Seca is home to a branch of the Skip Barber Racing School, which conducts race and street driver training in the paddock area and on the circuit itself on a year-round basis.

On August 20, 2006, Toyota F1 test driver Ricardo Zonta set an unofficial lap record of 1:06.3 The previous record time was 1:07.722, set by Hélio Castroneves in a Penske Champ Car during qualifying for the 2000 CART Honda Grand Prix of Monterey. The unofficial record was re-taken by a Champ Car on March 10, 2007 by Sébastien Bourdais, who lapped in 1'05.880 during Champ Car Spring Training. The unofficial record was again re-taken by a Formula One car on May 19, 2012 by Marc Gené, who lapped in 1'05.786 in a Ferrari F2003-GA during the 2012 Ferrari Racing Days.

Officially, Castroneves is still the recordholder as the times of Zonta, Bourdais and Gené were set during exhibition and testing sessions, and official records can only be set in race conditions (either in practice, qualifying, or during a race).
