How Many?

One
Not too much as it's only for fun
Two
Should start going as it's past curfew
Three
Starting to lose my vision and can't see
Five
Must get into car so I can drive
Six
Gotta stay focused as my mind is playing tricks
Seven
Somethings wrong must be the engine
Eight
Someone in the headlights gotta hit the brake
Nine
Both in the hospital with a fractured spine
Ten 
How many more times, will this happen again?
