I am also a driver and would have no problem with driving my minis bitless and blinker-less. (I do drive my minis in bits) The problem is finding the equipment. You can find bitless nosebands on Ebay. Then, all you would have to do is attach it to a mini sized English bridle. When I was riding, I quite enjoyed riding my horses in a bosal or using a bitless bridle. If a horse is going to take off with you, they will run right through any piece of steel you can find to put in their mouth. The only problem I see, is if you compete in driving shows, especially sanctioned by ADS, they do not allow a bitless bridle, however, they do allow blinker-less headstall. Don’t get discouraged and enjoy driving! GO BITLESS!
