There are a lot of excellent cars which meet the prevailing design requirements for cars. There are al lot of cars which have characteristics which make them a delight to drive. Nearly all cars are insurable for most drivers, All cars can be damaged, without incurring really expensive aircraft repair costs. All cars can sustain minor damage, which is permitted to go unrepaired for the rest of the life of the car, as it only affects the cosmetics of the car, not its operating characteristics. All cars can be loaded with some disregard for weight and balance, and still driven safely.
