The Clippers' training center was certainly one of the newer ones in the NBA. The previous boss of the Clippers had spent $4.9 million to purchase the land in 2005 and spent three years erecting a new training center.
Three sides of the training center faced the sea. It was within a mile of the beach and it was also close to the airport. The Staples Center was more than a dozen miles away. The training center was opposite the highway, so it was considered to have traffic connectivity.
The United States was, after all, a country that relied on cars. Regardless of wealth, everyone had a car. The public transport system of the U.S. has always been criticized. If Americans didn't have access to cars, their lives would change dramatically. Americans lived close to highways, just as the Chinese lived close to subway stations.
