If you don’t have any recent excessive travel history in and out of Thailand you can leave and re-enter on another visa exemption. You ask how many times you can repeat this cycle. There’s no official specific limit or regulations regarding this and everything is in the discretion of the IO you’re standing in front of and there for sure is a limit somewhere. If they mean that you aren’t a genuine tourist but use tourist solutions for long term stay in Thailand you risk to get pulled aside and told to get a proper visa according to your travel pattern and/or denied entry. I would say if you maximise two visa exemptions in a row and stay for 180 days the rest becomes a gamble.
And if you update your insurance for another year and get stamped in short time before 11th November 2025 you can stay until 10th November 2026. For your second year you’ll need to purchase re-entry permits as the visa itself it’s expired and you’re on permission to stay.
When status is changed to “Finnish” you’ll have an e-mail with your visa as a pdf as Stuart states. (You can also open your e-visa in the e-visa portal).
I’ve seen feedbacks of people allowed to convert to Thai licence only with a national driving licence from an English speaking country.
We could convert only our Norwegian licence previously if we got a confirmed translation of our licenses from our embassy in Bangkok. The embassy has stopped providing this service, so now it’s no way around a IDP to convert.
I’m sure practice regarding this varies between DLT, but it’s wort a try to check this up.
Tourist extensions are normally done within one or two days.
Some immigrations only let you apply within the last week, although most accept 30 day prior to due time.
I suggest you just go and get handed over their requirements. Normally you’ll need your passport with copy of ID-site and last stamps, one pass photo, receipt of your TM.30 address registration if they’ll ask for it and 1900 baht in cash. You apply on a TM.7 form at the immigration and can just ask your hotel or landlord of a receipt of your TM.30.
