"Up to" starts at zero. I'm sure that there are gains to be found, but numbers like those sound cherry-picked. Worzel August 17, 2020 02:43 AM Does this lock out the starter if it fails? Mike Johnson August 17, 2020 06:35 AM Neil: This is a wonderful article about in process optimization of some system. A great deal can be done here especially with heavy transport and EVs and autonomous. Francis August 17, 2020 06:52 AM Brilliant idea! Far too long have car owners suffered through expensive maintenance issues like worn tires and poor gas mileage. However, here in Canada snow, salt and cold plague us all though the deteriorating electronics to the aforementioned. if this product makes it to market, I wish it to be robust in construction! 666 August 17, 2020 09:09 AM Awesome, so proud to almost have been an engineer, but I’m still a massive revhead. The concept is brilliant. WTF didn’t anyone think of it before. The closest I can think of is the Porsche 928 which used rear wheel steering using suspension geometry and flexible mountings. sidmehta August 17, 2020 10:14 AM If it's running with a small contact patch and you slam the brakes in an emergency, how long does it take to react and give you a full contact patch? If you start skidding (or aquaplaning) before it reacts then it's not safe. So it needs an intelligent link with brake pedal sensors with fast reaction times to tilt the wheels back to a full contact patch. Sadly there is no talk of safety in this article, so we don't know. Signguy August 17, 2020 12:08 PM Did I miss the cost? It's got to be affordable compared to normal maintenance. paul314 August 17, 2020 01:10 PM Can't wait for the first set of hacks. (Albeit this sounds like it only makes relatively small tweaks compared to what you can do mechanically with stupid suspension changes.) Bruce H. Anderson August 24, 2020 07:10 AM This reminds me of 4-wheel steering, which made it way into automobiles and trucks 30 years ago and are remembered as "Too expensive, insufficiently practical, but totally wonderful." It will be interesting to see how this plays out.
