You might be interested to learn that radio waves can travel well in excess in of 90mph. as can helicopters. In fact, many jurisdictions ban high-speed chases, specifically because they are more dangerous than they help.
I think I'm perfectly aware of the existence of radio waves and the breakthrough in communications their discovery unlocked, but I wasn't talking about that. I was talking about two different objects traveling at two different speeds in the same direction being physically incapable of meeting at another point unless the faster object slows down or stops, or in this instance the slower object breaks the speed limit and speeds up.
It's a bad point because police already do radio ahead while they're in pursuit. Also, some cities do not allow police to chase suspects but it all depends on the crime. For example, they may chase someone wanted for murder but not someone else who's wanted for a non-violent crime. The argument is that it's not worth putting the public at risk for some offenders but for others it's important to apprehend the suspected criminal.
