I'd like to see a heated steering wheel.
For many, they'll consider it a "luxury" that is not needed. From my perspective a heated steering wheel is a tool. It allows me to work longer hours and be more productive. I own a small home renovation company and frequently have to work in the cold. Two trucks ago I purchased my first Ford SuperDuty and the option package I selected had a heated wheel. I bought it in the summer and though I'll never use that. Oh, how I was WRONG. Getting into the truck and holding that wheel and warming your frozen hands is perhaps the best thing ever, and yes, I'm considering all the things an adult experiences. It is that good. So, seeing as Ineos is marketing the Grenadier essentially as a tool, this is a feature that tool should have.
Ineos, you've already got heated seats. I hope you'll have a heated wheel too.
