In the movies, the participants in gun battles hide behind vehicles. In fact, bullets go easily through the aluminum sheets of which cars and small trucks are made.

The design is spare as it is made of steel, which is more difficult to mould than aluminum.
In any case, it won't be on the street for at least two years.
