What traffic accident are the speakers talking about?

M: Did you hear about that kid who was knocked down on Junction Road the other day?
W: Yes, it was awful, wasn’t it? Still it’s hardly surprising, is it?
M: What do you mean?
W: Well, there’re always accidents down there, aren’t there, especially with the speed cars go at. And, well, basically, the crossing’s in the wrong place, isn’t it? I don’t know why they’ve never moved it. I mean, it’d be better if it was exactly opposite the shops, wouldn’t it?
M: Yes, I know what you mean. They could do something to slow the traffic down, couldn’t they? Maybe they could put sleeping policemen there or something like that.
W: Yeah, maybe—maybe one every so often would help, but what would be really great is if they had one of those speed cameras.
M: Big Brother, you mean!
W: No, they really make a difference. You should see how they’ve slowed the traffic down where my parents live.
M: Yeah, I suppose you’re right. I’m only against them because I got caught by one last month.
W: You’re kidding!
M: No. A hundred and fifty pounds it cost me! A fine and six penalty points!
