Driving vehicle technology hasn't stood still. There are, and always have been improvements a couple of mine are bang up to date. So why has the maker gone off on a tangent like this, it's odd. It's like the equine equivalent of a Sinclair C5. I am 100% not, part of the formal driving brigade or 'establishment' and use my horses/donkey for leisure a lot of pleasure
and light work. TBH I can't see much practical use for the chariot. If it was any use I'd be the first to sing its praises. If someone wants one for light exercise on even ground then it could fulfill your needs. I don't know how it can be marketed as useful on a smallholding? The most useful horse tool on a smallholding is without doubt is a general purpose cart. We've had ours deep in the woods picking up logs I'd cut earlier with a chain saw, loaded with fence posts and fencing, taking rocks down to a ford and loaded with horse muck. As for blinkers that depends on their temperament not what's behind them. My Icelandic (RIP Vinnie) or donkey never needed blinkers, all the others do. I am not in any way a Luddite or stuck in my ways and will continue to look at all new innovations objectively and without bias.
P.S. I never have a groom either, but that doesn't mean I'm less safe than a saddle chariot user. If people enjoy theirs, great. Useful on a small holding I can't see how.
