Drive on the left
It would appear that the 'Drive On The Left' switch doesn't work anymore. I've tried it with an SVE and a new game and road transport is driving on the right.
I'm using PAK64.243 r2970 and PAK64.241 r2970 sve. It's also the same in PAK128.786 r2970. It may be r2970 which is at fault.
Sorry, I've just retried with r2967 and it's doing the same.
