Hopefully with this patch the devs might just have struck the ideal compromise between the two 'factions'.
The realism fans have got a major improvement in that cities are no longer 90 kph but 60 kph, a significant drop in speed and one that makes city driving a lot more realistic feeling.
The gameplay fans have got an improvement in that the country is no longer 90 kph but 110 kph, enabling better progress to made if a player wants to, but without being so fast that it becomes difficult to handle the truck and/or cause a nuisance to other players.
I think it has to go down the compromise route because from looking at player numbers over the past days (and even before GTA V), it's becoming obvious that most of the time the numbers aren't large enough to justify separate servers, especially with the problem created by having only 1/3 to 1/2 full servers, of lack of involvement and multiplay when you drive an empty world.
So, let's hope this might work in everyone's favour (or at least, the majority anyway).
