The figures

I owned my Mercedes E Class estate for nine years and drove it 116,067 miles. I put 14,822 litres of diesel into the tank over that time at a total cost to me of £20,470 or thereabouts.

Much worse than that, though, is that over that time I contributed 39.7 tonnes of CO2 to the atmosphere. That is the main reason I wanted to make the switch away from fossil cars.

The Model X was more expensive than the equivalent diesel car (though it’s hard to compare, really, as there is no direct equivalent as any EV driver will tell you once they own one.)

More expensive to buy to much cheaper to run

But servicing and running costs will be considerable lower. The Mercedes, which, incidentally, was the most reliable I have ever owned, cost me about £700 a year in servicing costs excluding tyres and extraneous costs such as body repairs etc.

I would expect my Tesla to be a fraction of this as it doesn’t have oil or oil filters to change and has brakes which don’t wear out.

And running costs will be significantly reduced. I estimate it would cost me £6,134 for the electricity I will consume over the next nine years which means I will save over £14,000 on the running costs of the Merc.

Oh, and by the way, my electricity comes from Ecotricity and is entirely green.

Autopilot issues

Today’s 300 mile journey to Norfolk and back gave me a chance to test the latest over-the-air software update 2019.40.2.1. This one was meant to bring more confident automatic lane changes among a few other things.

My experience today was pretty mixed. Navigate on autopilot was not available for the first half of my drive for some reason and the navigate was, but auto lane changes other than the car’s recommended ones weren’t working at all.

On the other hand when it was working navigate on autopilot was much more snappy in recommending a lane change into both a faster and a slower lane. It felt much more like a human driving.

Hopefully we’ll be getting a patch soon. If it was all working it would be very much more functional that when I bought the car six months ago.

Note: in Europe the rules mean we have to confirm autopilot actions unlike in the US.
