My Jack Russell is easily intelligent enough to drive. Last weekend he watched our grand-daughter being pushed on her trike seat then as soon as she climbed off, he jumped up onto the seat and put his paws on the handlebars, to the amusement of all.
However, he would never pass a driving test because knowing him he would use the car to run over the nearest German Shepherd or Great Dane; which he would normally attack. He has no perception of "hazard awareness".
Thankfully he can't reach the pedals anyway!
