lol the speeds are in KM/H That would mean that you would have cars flying over the road at 300KM/H i changed them once(just for fun) i found that a police car going at 160 is fast enough Firetrucks going at 120, and ems at 145. But it's something you need to decide for you self. The change you make is a factor for the event scripts. Murder will happen more than bank robbery with your current settings. But i'm not sure if they will happen more/faster over time
