Strange Observation Made On Route To Epsom

As a car passenger, shortly after leaving the house on route to Epsom, I noticed some lights in the sky which were not behaving as planes.

I kept an eye on them for a minute, knowing that plane flight paths can be deceptive. They seemed to be moving very fast, then one stopped. Another disappeared completely. Within a few seconds the second one seemed to be back again and as we turned the corner, appeared speedily to be playing tag!

Looking again (lampposts, trees obscuring sometimes) there was then a plane, (I presume, given the normal flashing lights on it) and a small bright light sped to be close to it and appeared to be following its course.

From the other side of the white light an object with lights resembling a helicopter, appeared to draw in, a second or so of 'chase' then the 'helicopter' turned away.

Opening the window, I noticed no sound. The objects were on our left. We turned left towards Epsom and, despite the main street lighting, I could still glimpse the white light almost in front, which it should have been as we had turned to the left. Further up the road I noticed it on our right, but we were on a straight road. At Ewell Bypass traffic lights, the light was in front of us. I remarked to my driver about the light again. He said it was a star, or Venus. I said that I was sure it wasn't; I dont look out for ufo's, but my attention had been drawn to this. We turned left towards Epsom. Straight on, at further traffic lights, the light was at 10 o'clock position. Given our route it should have been at 5 o'clock position. My driver could say nothing. On arriving at Epsom, with no veering off, even he had noted the position of the light, which was stationary. At an 11 o'clock position to us now. This was a maximum 15 minute journey, and the white light occasionally 'disappeared', reappearing in these various locations.
