We all need help obeying the law.
If you look carefully at the bottom left corner of this photo, you’ll see a “Bus lane cameras” sign, reminding drivers that if they drive in the bus lane, a camera will take a photograph of their license plate (or “registration tag,” as it’s called in London, where I took this pic). Then the government will send a large fine to the driver for breaking the law.
This little system allows buses to move much faster than if the bus lanes were clogged with cars who shouldn’t be there.
Similarly, in my state, red light cameras are at almost every intersection. It’s the same deal – if I run a red light, I will get a huge fine. It amounts to a tax to help cash-starved local governments – but it also keeps me from running a red light.
What enforcement system in your world keeps you on the straight and narrow?
