Think about the article. Why were only two Volkswagen Beach Bomb buses made?

The buses moved slowly.
The buses tipped over.
The buses cost too much.
The buses were too pink.

The most likely reason only two Volkswagen Beach Bomb buses were made is that they tipped over easily. This made them unsafe and impractical for production and sale to the public. The other options - the buses moving slowly, costing too much, or being too pink - are less likely to be the reason for only two being made. Safety concerns would have been a primary factor in the decision not to mass produce the Volkswagen Beach Bomb buses.
