@Byron - Force = Mass * Acceleration(not Velocity) In an impact, equal forces are applied to the objects involved (in opposite directions). This means that when there is a crash with a large vehicle and a small vehicle, the smaller vehicle will have a greater acceleration. The smaller vehicle will stop more abruptly than a larger one, causing more injuries to the passengers. You might want to read up on the "Laws of Physics", specifically Newton's Second Law.
That said, small cars can still be safe if properly equipped. Also, there is a difference between accident prevention and safety in an accident. A large car will fare better in an accident because of Newton's Second Law. A small car may avoid accidents easier because of a low center of gravity or other factors.
