I made a couple of runs out of Phuket last year. They really drive fast. Then I flew to Kuala Lumpur. Hard to say which was scarier. Now I drive my Honda Click to Cambodia. It's only an hour each way and the roads are safe.
I think it all depends on where you start. And you might regret not bringing a helmet no matter how you decide to travel.
I do it in multiple deposits. The bank statements verify. It's not a problem at my immigration office. Every office seems to have different requirements.
Never an easy task for those of us with bad knees. I never leave home without tissue. I just don't feel comfortable with a soggy butt! Always lift your tail. 🐒🤣
