The expense of Formula One has seen the FIA and the Formula One Commission attempt to create new regulations to lower the costs for a team to compete in the sport. Cost-saving proposals have included allowing customer cars, either by teams purchasing a car from another constructor, or the series supplying a basic chassis and engine to some teams at a low cost. Allowing teams to share more car components such as the monocoque and safety components is also under consideration. The FIA also continually researches new ways to increase safety in the sport, which includes introducing new regulations and accident procedures.
