We loved the playful cleverness hidden down in the footwells of Nissan's two Pivo prototypes: this year's Pivo 2 features music-player-style fast-forward and stop iconography, a sidestep from the pedals featured in the earlier egg-on-a-rollerskate Pivo 1, with bold add and subtract symbology.

We're unlikely too see either option on a Nissan forecourt any time soon. There's nothing in either Pivo that couldn't be done in a production vehicle - but Nissan has said the cost of swivelling cabins would be prohibitive. Plus, of course, big car corporations tend to water down the creative exuberance in the transition from motor-show to showroom, losing many of their charming little details.

Smaller makers, by contrast, tend to be a bit more adventurous - often bringing the wow factor through to series production, in a bid to attract attention if nothing else. Look inside a recent TVR, for example. So we can only hope that Brazilian micro-sportscar maker Obvio! will bring its fabulous flip-flop style pedals to market.
And, equally, that Aptera's plus and minus pedals will survive through to customer deliveries.
