This is my personal opinion, these issues are not a major factor but they do annoy me. I will have a separate post about more significant challenges.
Driving. I think Georgian drivers are the worst drivers in the world. Not getting into a lot of details – come and experience this for yourself, then see if you agree. Certainly worse then even in NY, and I thought NY was pretty bad. (Though I think Boston drivers aren’t great either). In Asia (I’ve only been to India, Nepal and China, can’t speak about more) at least drivers are generally more careful, less aggressive and drive slower. And I’m not only talking about BMW and Mercedes drivers – that’s pretty much a given. A lot of people drive very aggressively, zipping through multiple lanes, many drivers either do not know the rules or just don’t care. They can’t figure out what those white lines on the road are for and completely ignore them, so you get at least 3 or even 4 lanes of traffic on a 2-lane road. Turn signals are uncommon, and going to an exit from the opposite side of the road across 4 lanes of traffic is very common. And I’m not even going to mention parking.
No Amazon or even a close equivalent. This is a major inconvenience. On of the hardest things after moving here is figuring out what to buy where, and sometimes it takes a while to find who may have what you are looking for. And while some of larger stores can deliver, not all do. There is a possible workaround to order from the US or EU (I use Amazon UK for 220V electronics), but you pay shipping to Georgian forwarder companies (around $10/kg) plus for anything above ~$100 you have to pay 20% VAT here to Georgian customs. And orders from US/UK take at least 2 weeks to get here, and add another 1-2 weeks for ones that you need to pay VAT for.
Smoking. Unlike US and even EU, a lot of people smoke, including a lot of younger people. At least most restaurants have smoking and non-smoking areas, but when the weather is nice and you want to sit outside – you are most likely to “enjoy” cigarette smoke stink as those outdoor areas are for smokers.
Street dogs. There is a lot of them everywhere (maybe less in Vake), and for some odd reason they tend to bark ALL NIGHT LONG. So to sleep with open window/balcony is next to impossible unless you are a very sound sleeper or wear ear plugs. During the day the dogs are pretty friendly and not aggressive, give your food scraps to some local ones that live near you. Watch out for their souvenirs on the pavement, and though this is one of the most mentioned annoyances I saw on YouTube by foreigners – I did not notice this too much, definitely much less of a problem then human crap everywhere in some US cities (especially in California).
No street names or house numbers in suburbs. I live just outside of Tbilisi, in a village, and only a couple of most fancy streets here have street names and house numbers. Which makes getting mail extremely difficult, and same goes for address for deliveries and taxi rides.
Slow Internet. Even fiber service here is limited to 100 Mbps, while this may be sufficient for basic use like video conferencing – streaming multiple videos on a single internet connection will be difficult, and if you work remotely (which you kind of have to if you are in IT), your capabilities will be limited by the bandwidth you can get.
Local beef. Local beef is very very tough, and you won’t find US-type standard cuts where there are the same cuts under same names anywhere you go. Even better looking cuts here are not good for steaks or frying – they need to be marinated and slow cooked to be eatable. Angus beef steaks are available in gourmet stores – but they are very expensive and usually frozen. So I understand why locals prefer mtsvadi from pork (or even chicken), it is just not possible to prepare it from local beef (I tried a coupe of times, using different marinading techniques, and failed). Lamb mtsvadi is very hard to find as well. Local pork is very good, both taste and quality, so if you do not have religious reasons to not eat it – I recommend going for pork (or chicken) dishes that are not cooked for a long time. I think this is also a reason Georgia is not a steak culture, at all.
Roads. The roads outside of big cities, or even inside of them are really bad or non-existent. Highways are mostly fine, but local roads in smaller towns and villages are gravel at best (or dirt). If you are buying a vehicle here – keep this in mind, and aim for AWD.
Lack of credit system for foreigners. It is pretty much impossible to get a car loan here, so you pretty much have to pay cash. There may be some better availability with mortgages, but it is very risky due to no local job opportunities, so it makes more sense to pay cash for properties here, but not for cars.
