This causes an enormous back log in one lane, thus the traffic is unable to flow. It is so stupid. Suafoa When driving on the freeway, I often find on-ramping cars merging into my lane driving soo slowly that I have to slam my brakes. It's like they don't stop to think whether or not other people are already on the freeway. I also hate it when other cars merge into my lane and continue to travel at their own leisure speed, while behind them I as well as all other ten trillion cars hit the brakes.
People seem to obey the speed limit much more than over here.
In Hawaii, people are always waving you into their lane. It really is a treat to drive in Hawaii, at least for me. It's all because of impatience. No turn signals, cross solid lines, can't merge and slow in the fast lane. Inconsiderate drivers who just change lanes at the last-minute without signaling.
