>>1831286you can hit a pothole at speed. Road bikes are designed to be ridden on rough country roads and on gravel.
There are mountain bikes with carbon forks (and frames).
Your wheel will fold up before your fork.
It's not a weak material and it's not something they underbuild, because that would be a serious legal liability and kill people.
>parkingI mean you have to be careful generally because if you put a deep scratch in carbon it's sketchy. The same is not true for a steel fork. Like you really do not want your bike falling over onto concrete.
