Hello; If this were the first car ever made, we could have skipped building roads. Police force just purchased one for search and rescue in Canada. They did a demonstration and the thing is amazing! Engineers everywhere: ok we need to think about suspension, ground clearance, weight distribution, power distribution and much more. Seen these several times. Absolutely amazing vehicle. But, I still think sometimes a tracked vehicle might have just the very slightest of advantage over these. Depends on the exact terrain though. What a little monster truck! Awesome performance and simplicity at it's best. Props to the designers and engineers that created the SHERP!
