Before 20 years, I was surprised at big scale cars on right side in Los Angeles.
In the sunshine wide road, a lot of cars run smoothly on free way in high mood.
About 10 years later, I was also surprised at double parking of small size cars on both sides in narrow road in Rome.
I wondered about the inside cars how to ride on the rightly right road.

In Australia I had feel-relieved conduct at last.
As you know cars in Australia and Japan , of course U.K. , move on the same left side. Sizes of cars are also familiar to me. A car number plate of Queens land state was written
" Sunshine State "
and makes me very relax.
The plate number is made of three alphabet characters and three numbers and colored with yellow, green, and black which colors are different from states. And if you like, the plate numbers can be proposed by your own likes six characters. I feel more relax on that number plate choice. Australian car is checked every year more easily by registry compared with Japanese car inspection. On the other side, I conceited the car accidents in Australia may be more than those in Japan. But even if I considered wide land and low car density in Australia,
I am sorry that the traffic accidents in Japan overpower that in Australia. A lot of signals mean to conduct us on the right way. However the signals inversely gave us uncertain safe. Yellow sign which means almost red sign gave many drivers as almost green and hustle sign. Then, a lot of traffic accidents occur at crossing. I feel anxiety with no signals at crossing in Cairns and Gold Coast. I also find alternative rotary and approach roads to right turn . And more, I have to be careful to cross the road by myself. It is very valuable occurrence of no depend-on the signals.

I need no attentions to traffic conditions on sightseeing bus. I had no caution to the traffic signs of kangaroos, horses, and sheep. I feel relax on Australian bus.... However, I found the same scenery from the window in rotary, since our bus driver rounds the car in rotary with weird laugh.
Bus guide said in rotary
" Again...., we have enfolded in serious traffic accident .
We need some APPLAUSE to the driver for escaping from the rotary"...

Therefore, in Australia I had to have an another traffic accident in every crossing.
