Why hovercraft are not more common?

Answer 1

Hovercraft are becoming more common, and as technology improves, they have become quieter and more affordable. Hovercraft are very useful for rescuing people from floods, mud, ice and sand - as global warming increases the risk of flooding, as witnessed in Pakistan and China, hovercraft can play a very important role. Leisure hovercraft are now available, see the related link below, and small patrol hovercraft can play an important role in homeland security, particularly for patrolling coastal areas. Small race hovercraft have very thin lightweight hulls, but with the introduction of other materials such as HDPE, hovercraft can be lightweight and durable. I THINK THEY ARE NOT MORE COMMON BECAUSE THERES NOT THAT DEFINITE CONTROL OF THEM THEY DONT STOP FAST LIKE A CAR

They have their place in difficult terrain, but they are really not fuel efficient. So, they are not typically used outside of those special circumstances
