In the last two races we have seen wheels flying off crashing cars. Today, Piquet removed his entire front suspension and threw it all over the place. I was under the impression that the (front at least) wheels had to be attached to each other by a "rope" to prevent this. I looked several times at the previous race crashes and at todays. There was no evidence of this attachment system. Has it been removed from the rules and if so why. As I said, a complete wheel assembly and suspension went rolling across the track today. Run into that at speed and it will really ruin your day and maybe permanently.
