Okay kiddo, so you know how sometimes mommy and daddy take you on a trip to the city, but it's really hard to find a parking spot there?
Well, in the UK, they have something called a "Park and Ride" service. This means that you can drive your car to a big parking lot outside the city where there's lots of space to park. You leave your car there and then you get on a special bus that takes you into the city.
The bus is really big and comfortable, so you can sit down and relax while it drives you to the city. It makes a few stops along the way to pick up other people who also left their cars at the parking lot.
When you get to the city, the bus drops you off at a special bus stop that's right in the middle of all the fun stuff to do. You can go shopping, see a movie, eat some yummy food, or even go to a museum!
When you're ready to go back to the parking lot, you just go back to the bus stop and wait for the special bus to pick you up. It takes you back to the parking lot where you left your car.
It's really cool because it's a lot easier to drive to the parking lot than to try to find a parking spot in the busy city. And it's also better for the environment because lots of people can share one big bus instead of all driving their own cars into the city.
So, that's what "Park and Ride" means. Do you understand it now?
