please think it simple
for example:
2 car start at the same time, they both speed at 180 miles/hour
so for you, you will see no car at your front, but you can see your car next to you and he said "hi" to you

so for your case,
I think you can see your car light ball is "lighting"
but the road is still "dark"
then you may think: "Ghost did it?"
and said "HELP~~~~~~~~~~~~~!!!!!!!!!!!!!!!!!"
