Hi!
I'm having same issue since 2 weeks. I cannot drive my car at low speed nor my airship. Inside a sim, I have no lag issues, but when I pass a sim crossing I loose control of my vehicle and my camera goes nowhere. Sometimes, (only sometimes) it gets back after 2minutes. It seems, however, that co-pilots don't have this issue.
Hope you can fix this problem very soon
Regards,
Estrella
