Why did you bother asking this bunch of tw@ts for advice? Surely you knew their answers before posting? The reason they have run to Thailand is because they don’t have enough gumption to be anything in their own countries. Note that no one has actually answered the questions you asked.
If the daughter is being cooperative start with them signing a written statement admitting liability. Keep screenshots of online conversations in case they block you or dump their account. If it’s not progressing in your favour in a couple of days, go to the tourist police and get them to liaise with the traffic police for you.
Don’t just roll over and accept it. Losers doing that is exactly why the Thais think they can get away with it.
To almost everyone except the OP, call me anything you like I turned off notifications so you’re talking to yourself 🤣
Meh, you get used to it. Take it from a Brit that nearly always has to drive on the wrong (right) side of the road. Also we drive our right hand drive cars into Europe a lot. Obviously it’s slightly more awkward but not a significant problem. And yes I appreciate Thailand traffic, I’ve just finished three years in Vietnam. It’s even worse there.
Bottom line, he’s not bringing his truck any more anyway 🤷♂️😊
