A few days ago, our roads were very icy and slippery. I lost traction with my Fit a few times...it still has the summer tires on.
I remembered when I got home that I had the Sprint Booster set to one of the highest settings...so I turned it off to avoid the spin-outs.
The next day, forgetting that it was off, I almost pulled over thinking I had a flat tire.
Driving it now, without the Booster-normal throttle, is like driving thru mud.
The roads are clear again, so I switched it back on. My Altimax Arctics are going on soon.
