You probably all noticed that on hotlaps when you hit a wall or hit the grass with more than 2 wheels your hotlap wont count.
Now I was hotlapping South City the other day and because I am a sloppy driver in the RB4 I kept hitting the walls. Thing is, I didn't get a single message that my hotlap wont count. So now my question (and improvement suggestion) is : why dont the walls in South City give you the message that the hotlap doesn't count? Hitting a wall in Blackwood or hitting a wall in South City is the same right? a wall is a wall?
I also noticed that on so3, when you hit the wall on the last corner you can gain a lot of speed, still you wont get a message that the hotlap wont count.

This was mentioned in another thread and it seems that the walls don't detect crashes.

The world record holder (driving the RB4) believe it or not used the walls to rapidly slow their car down after coming down from the bridge at a certain SO track.

Your driving isn't sloppy btw

Ow ok sorry for the repost, I searched but seems like not good enough.
