I'm not sure if we're reading the same post here. Let me summarise how I took events:
OP = Ted
Car in front = Bill
- Ted is driving behind Bill on a road. They are both at the speed limit.
- Ted is in a rush, so he decides to overtake. This requires Ted to drive 10mph above the speed limit, and position himself in the middle of the road.
- Bill, feeling concerned at the car behind him increasing his speed, when he really shouldn't be, speeds up so as not to crash. Had Bill not increased his speed, this could easily have happened:
- Fortunately for Ted, he has space to go back into his lane when a car does approach towards him. If Bill had not sped up, Ted could have blocked the oncoming traffic.
Overtaking should never exceed the speed limit. I'll admit that it was wrong of the driver in front to accelerate, however it was clearly extremely dangerous driving by the OP and the driver in front can't be blamed for his actions, it may well have avoided an accident for the OP. That might be why he slowed you down.
Moral of the story OP: Drive better.
