I love my 1 month old Tesla MX and try to be kind to it. One of my pleasures as an old man is seeing if I can keep the watts/mile average down for each trip. However I did it again today. Coming back up the road from Edinburgh and after all the interminable roundabouts round Dundee I come out of the very last roundabout, I eventually hit the derestriction signs after all those 40 and 50mph stretches. The road in front is relatively clear, steep uphill, dual carriageway and can I resist putting my foot down? Away I go passing all the other cars on that uphill stretch with a big smile on my face, then I look at my energy useage. What have I done to my average, no way am I going to recover all that. Why on earth do I do it every single time?
