Never heard of this. I used to drive around my park opposite my house everyday, even in muddy conditions and never had an issue.
also iused a scooter cover like this.
I paid about 140.00 for it but it lasted 7 years. you just drive in and pull the top down. you can attach something to do that. it never lifted as it was fitted to paving stones. best money i ever spent. I used to find the covering more hard work with those loose ones.
My scooter also had a high clearance OFF THE GROUND and was make for all terrain. If you have one that is not all terrain you may have issues.
