In the mean time, Some more new info I've found translated at GTAForums.
- Lola is available for special hours.
- You can't take the taxi ride, while police are after you.
- Police will appear on the map as 'dots', while they are on search for you.
- The map will have GPS, which shows you the best way (will be colored in Yellow) towards your target.
