I guess so. I assumed the challenge would be more of the ramping up of the other events, like more takedowns per Road Rage, or faster opponents in races. Which I've noticed some of that but not a lot.
It just sort of hits me. The rest of the game so far has had stuff be challenging but I hadn't hit something that I simply was not capable of doing. Its into the frustrating level of difficulty instead of just being challenging and fun.
Part of the annoyance I think is the crashes/timer. Time slows down during a crash, but the timer does not. It ticks away at full speed no matter what. So crashes eat up a good 10-15 seconds and when you've only got 2 minutes to get there you can pretty much kiss it goodbye.
Luckily I can just do more events and unlock a couple more cars, but its going to be a little annoying knowing there will be those last few unlockables that I won't get to drive.
