I was driving along the road when a red car sped past me.
That sounds dangerous. Was there an accident?
No accident, but it all happened so quickly, and I was quite scared.
That's why it's important to pay attention when driving. You need to be aware of your surroundings so you can be ready for fast moving vehicles. If you aren't, you can easily get in a car crash.
I'm glad I didn't because that would have been a waste of my perfect driving record.
It's good that  you are safe and nobody was hurt! When you are driving you need to be alert in case another driver does something erratic. Otherwise, people can be killed.
