You've only told us that you're scared of being mugged by dealers! That doesn't even count as anecdotal evidence that it's likely.
Got my car totalled on the m40 by a teen with a license of 6 months who was clearly on his phone - that one I was for sure lucky, could've easily been the end of me. The police? Didn't even show up. My police report that I filled out while still shaking got a response letter of "We don't care m8".
