There are far better solutions to this ITireFactory problem than PHP, which puts the tires directly onto the car, but forces you to buy a new car as soon every time you get a flat.

Also, the tires are likely to explode every 16 left turns unless you know about the secret tire fixing button under the dash.

It is true that PHP may save people a few hours in the beginning, but at what expense? How longer does it really take to get a noob running a Sinatra, web.py, dancer or something similar?
