The Highway Traffic Safety Institute report listed many cars in other classes that had more injuries per accident than did the PZ 1000.

In recent years many more PZ 1000s have been sold than have any other kind of car in its class.

Cars in the class to which the PZ 1000 belongs are more likely to be involved in accidents than are other types of cars.

The difference between the number of injuries per accident for the PZ 1000 and that for other cars in its class is quite pronounced.

The Highway Traffic Safety Institute issues reports only once a year.
