Glad you like my idea. I was going to suggest that you add a red flashing light to the police car, but after zooming in, I see that you did provide one along with an alternating blue light. Nice job!

Feel free to embellish the scene with roads, buildings, obstacles, or any other ideas you have.

Nice fix for the lights. They are more visible now.

Okay, time to nitpick...... When the scene starts, a person hardly has time to think about pressing a key when the police car is already on top of them. So, maybe change the starting process with a countdown timer, OR start the cars moving only after one of the arrow keys has been pressed. OR..... simply separate the cars a little farther from each other.

... OR wait long enough and you will fix it. That works for me.
