Why do I have to change?

I bought a car recently. It's a Ford Focus. It has an automatic gearbox.

I have driven cars with auto gearboxes for a number of years without any trouble. But what I have found is that this car does small kangaroo hops when I drive away from speed bumps in the road, as it kicks back from second gear into first to gain better acceleration. The car has had this problem virtually since I got it about three weeks ago.

After having it serviced the problem remained and so the head technician took me out for a test drive this afternoon. After driving it with little problem, the car did a couple of little hops. The explanation to me is that there is nothing wrong with the car. It is my driving style. Apparently I am confusing the computer which manages the gearbox. I have to change my style to suit the car.

Why?

I don't drive the car aggressively nor treat it poorly yet I have to change. The car can't be reprogrammed to suit me. Why not? If all the other cars that I have driven in the past suit my driving style, why can't this one?

It would be great if the car learned a person's style and adapted things such as gear changes, etc to meet that style. I am sure the technology is available. Who's going to create it?

But then I suppose this car is like other products I buy which don't quite suit me but I buy them as they are the next best thing to what I need. Is it possible to make mass produced products customised for each individual?
