Granted, stability control was off - but still, just sayin.
I observed one taking some S turns at speed on 1 just above Stinson a couple weeks ago... the thing was not composed. You definitely don't want to get 'sling-shot' off the Hwy 1 cliffs.
Dude that video is crazy looking, you see his head hit pavement and fold in.
I saw a gang of these losers pull up to Alice's Restaurant and man they thought they were the shit. Those are in the same category as the CanAm spider, they suck. They remind me of quad or even Harley riders. Ya I said it.
If I needed HOV access from a car, I think that would top my list. Leaf and the rest are expensive for the short range vehicles they are. Slingshot is less, goes farther and looks more fun. Also the trike's HOV access doesn't expire in a few years like the HOV stickers do.
