At work a business man sat at a desk for 8 hours starting at 5 a.m. and of course when you sit for 8 hours looking through boring papers, you become tired. He stayed up through will power and lots of coffee. As work came to a close and his co-workers began to fill out of the building, he collected himself, gave a large sigh, and headed for the elevator. He walked out the building towards his company owned van and started the engine.
While on the road he got a call from one of his co-workers. He said "I'm on your side of town and I know we have that business deal to finish, would you mind if I come over?" In response the business man asked "Do you remember where my house is?" his co-worker said "I think so" To this a meeting place was arranged and they both met at a small snack bar with their cars. They then continued to the house.
The single business man was driving alone in a van and was being followed by another car that never got 200 yards away. He pulled into a very thin, fairly straight, one-lane road that had no intersections with the exception of two driveways. The road was ~3 miles long and had a slope of ~20* all the way up. Towards the end of this road there was one bend to the right, much like a tilted backwards 7. About 50 yards before the bend, on the left side of the road, looking up, was our first driveway. After the bend, the road continued for ~100 yards before on our right looking up the road was our second driveway. The road then stopped at a dead end.
The business man drove up the road he lived, constantly looking backwards every ~30 seconds. Each time he looked back no one was there. On either side of the road were large trees that blocked any nice view, for the setting took place in a forest. As the business man neared his destination he pulled off the road for 1 minute, during which he looked up and down the road to make sure no one was following him. He saw no one. He then continued into the first driveway and stopped to open the gate. When he re-entered his car he saw a car in his rear view mirror:
Can you explain the events and how he was followed?
key: ~ means approximate
This is a diagram of the road
Correct so far: From @Benjamin Braun:
When he looks up and down the street the car has driven around the corner. When the business man turns into the first driveway, the following car comes back around the turn and follows him into the driveway.
