Jag F-PACE taught me a lesson on tyre size; Would you nap as your car drives itself?

Then I drove the 2-litre diesel on 20ins tyres. Totally different car altogether.

The point is that for all the gargantuan effort put into making suspensions so much better - and the F-PACE is set up for dynamism, no doubt about that - the incorrect choice of tyre size can make an enhanced or detrimental contribution.

Another thing . . they had a Special Edition version for us to drive over twisty, stunning, hilly roads in Montenegro.

I didn't like the rear bumper insert they had on these and said so.

Next morning we drove different models without the insert and the car looked a million times better.

It just goes to show that elements we can so easily overlook, such as tyres and little visuals, can often have a disproportionate bearing on how a car behaves and looks.

I was much fonder of the 20ins 2-litre diesel with no rear frippery. Can't wait to get the F-PACE on 18/19ins back here in Ireland. I think it has real potential.

I don't know about you but I have yet to invest enough faith in technology to be comfortable enough to take a nap in a self-driving car.

But in a recent Whatcar.com survey 26pc of people said they would be happy enough to nod off while the car was driving itself.

That's what I call real faith.

Would you trust a car to drive while you snoozed? Let me know

Extraordinary, but around 70pc of all Porsche models ever built are still in drivable condition, the firm says. An obvious problem is where do you get suitable tyres to keep them 'original'?

Porsche say they have developed tyres "properly tuned to specific vehicle generations" - including those released in coordination with Pirelli.

The new tyres match the "historic originals" on looks and profile design fulfil the requirements of modern generations of tyres.

They've come up with 32 of them for different models between 1959-2005.

Included are series 356 (B and C), Boxster (986) , 911 (G model, 964, 993 and 996) and transaxle model series 924, 928, 944 and 968.

* The Beijing Show is increasingly influential as you would expect with a burgeoning market. Audi debuted its TT RS (2.5-litre 5cyl petrol produces 395bhp means it is more powerful than a Porsche Cayman S).

And Lexus showed its facelifted IS. And Volkswagen's luxury SUV concept is widely regarded as the outline of the next Touareg (due next year).

I know it is probably stating the obvious but the extraordinary thing about Beijing for some time now has been the huge number of vehicles by European makes that are designed and made for the Chinese market alone. Quite a revolution is picking up real pace now.

* Really liked the look of the new Mullingar Autos Skoda dealership. Our best regards to all we met there on Monday.
