M: Morning, Julia! The traffic is really heavy today. I’m almost late!
W: Take it easy, Nathan. It’s really hard to drive at rush hours recently.
M: Yeah, some measures should be taken to change the situation.
W: So are there any rules or regulations that you’d like to change?
M: You know what, Julia, that’s an interesting question. I’m not sure that I want to change rules, but I’d like the police to be stricter on the rules. I don’t know why there isn’t a camera at every set of traffic lights just to stop people from doing that, you know. Or like speeding. Its very, very easy to put speed cameras in place, but people seem to think that it’s OK, like the speed limit is the minimum speed.
W: Maybe the car manufacturers should have some responsibility in limiting their engines. What’s the point in producing an engine that’s big enough and powerful enough that you can go like two hundred kilometers an hour when the speed limits are only…
M: Have you ever driven in Germany where they don’t have speed limits?
W: I’ve been to Germany and been a passenger in a car but not a driver.
M: I think people do drive responsibly. Often people break laws simply because the laws are there, you know. If the law isn’t there, people drive within their ability range on the autobahn. As far as I know, I think they have a high safety rate.
W: Oh, really?
M: Yeah, they have fewer accidents, because when you’ve got speed limits, this creates situations that actually present dangers on the road.
W: I guess in Germany maybe those people have better education about self-responsibility when driving maybe?
M: Possibly. They also have very good cars, very safe cars.
W: Right. And you know if you’ve got like a Porsche or something that can go at that speed then, it’s so nice to be able to do that.
M: Yeah. So I think it’s the restrictions that create the danger sometimes, based on the autobahn.
W: OK.
M: Obviously driving through a residential area (住宅区) or where there’s a school you’ve got to have…
W: Speed bumps (减速带).
M: Yes! Those speed bumps force you to slow down. I think they’re a good idea and perhaps the way to go.
W: So you don’t think fining people is useful?
M: Not really, no, because that relies on the police time, and the police don’t have time to police every single driver all the time.
