I love roundabout. It's very fun and it makes me pleasant. I think roundabout is an ideal system.
In England driving rule is the same as in Japan. (To tell the truth Japanese imitated English rule in the old days.) Therefore I made a plan to rent a car and drive in the countryside to see a lot of beautiful gardens.
That was the most important reasons. But I was anxious about one thing. How could I understand about the roundabout at the crossing? I have ever heard that we have seldom seen the traffic light in the countryside and the roundabout controlled all vehicles. I understood it's likely to be a rotary. Perhaps at that point all vehicles have to turn around it.
After that I have studied hard about roundabout to read many books, and finally I completely could understand.

A．Rotate clockwise at the roundabout
B．Give a priority to the car inside that, that is, the car from right has a priority.

These are the important things. I try to take an illustration intelligibly.
When you approach a roundabout (There is necessarily a signboard before.), if you will turn left you blink left and keep left, if you want to go straight you blink right and keep center lane, if will turn right or make a u-turn blink right and keep right lane, and slow down. At the entrance you can go into the roundabout if any vehicle don't come, if you see one you should once stop and you can go when you find the pause of vehicles. You should blink left at that point you go by the previous exit you want to go, and you can get out of the roundabout.
Even if it has many lane or not, the rule is the same basically. You can find an arrow, a direction and the number of the road, the name of the city on the road. You will soon become accustomed to the driving, I think. If you keep slow driving you will rarely be astonished with a horn. Let's drive safe.

There are various type of roundabout, that is, a variety of lane number, the width of rotary and the composition of it. If you will be familiar the roundabout it make you interested in the rule. As soon as I had understood it, my apprehensions have gone and I became a roundabout fan.
This system is the most rational and it keeps all vehicle's smooth driving in the countryside. Why isn't there a roundabout in Japan？・・・・I would like to say, but I already know the reasons.

As I am a master of roundabout now, I will introduce my technique. When you approach a roundabout you have to confirm the exit number you want go. At the same time you should prospect rough size of the roundabout by eye measurement. You keep suitable lane, slow down with checking the car from right hand and go through. The extend of the reduce is due to the size and the congestion of cars. In different words you can go through there without extra reduce when no vehicle comes. I get a special kick out of this driving.
Needless to say, if I can't find my way I have to turn it again and again. To guess at the first ,to confirm at the second, to go through at the third round. I have already experienced those. Roundabout is the most suitable for u-turn, too.
There are many reasons I am fond of the driving in the countryside, one of them is the roundabout, I am sure.
After all I love roundabout.
