@TheCheshireKhajiit - there won't be an evil trucker this time.

The developers stated that they won't 'develop' this part of the game - hitting pedestrians or buildings - at all, instead they'll focus simply on driving mechanics and add-ons for trucks. Well you can destroy your truck if you hit some heavy building, but it's not like GTA style, where you could go on a rampage. There are really a lot of various addons for trucks, like body paints, cabin accessories, chassis modifications, the list is so long, that not even I know what all it encompasses.
@Renee - the only license required is a valid account on Steam, I guess.
There are four different driving modes - two with mouse & keyboard, one with controller and one with wheel (and pedals, although they're not a must). Changing gears is possible only in the last two modes. I'm satisfied with the M & K approach for now.
You can listen to some real radios that are automatically generated as you drive, or you can insert streams of any world radio stations to an .ini file, and listen to any radio you want.
You can't chew tobacco unfortunately.

In fact except choosing a 'profile pic' and seeing the driver when rotating the camera around, there aren't other actions possible, you can't walk out of the truck. If you have a flat tire, there's a combination of buttons you must press to repair it / replace it, or you can call for help. I haven't yet experienced this scenario but I got a ticket for speeding today.
New Las Vegas exists yes, and it's available by default, without any DLCs. It's quite big, but not entire town is covered, you can only drive on predetermined roads. But apparently they made LV bigger with one of the latest updates. States that are currently available to traverse are: Arizona, California, Nevada, New Mexico, Oregon, Utah and Washington. The next big update / DLC will bring Idaho and or Colorado.
In comparison, ETS was released in 2012 and now, 8 years later, almost entire Europe has been covered, but there's still room for more. ATS was released in 2016, so it'll be at least 4 years and more to cover most of the USA, I'm assuming. Oh, BTW, Reno is also featured in ATS, alongside already mentioned Las Vegas, Carson City and Elko.
@Acadian - it actually wasn't my intention to run a double trailer, I was shocked when I saw in the side mirror, that the second trailer began moving as well as I accelerated.

In Europe it never happened that one of quick contracts would involve a double trailer, so maybe they changed it for the ATS, or maybe it was just a coincidence. One thing I noticed first is that lanes are wider in ATS than in ETS, just like in real life.
A good look at the Lopoved shot will reveal me (the driver) behind the wheel. To keep things simple, I'll refer to myself as the driver, because I also used my real name in the game.
