When my Tesla was 300 miles old I took it on a 3,000 mile road trip in the dead of winter. I learned its idiosyncrasies and how far it can go in real world driving. Since that trip I have Zero range anxiety.

Here are some tips. You don’t give details on your car (why not?) so I’ll assume a modern car with 300 miles of range.

• in an ice car there it’s a warning light that comes on when the gas gets low. I think of 10% charge remaining as that warning.

• when planning a long trip into areas with poor charging support always navigate from supercharger to supercharger. My routes look like this: first where I want to go. Second where I’m going to charge. Ideally I get to the charger with 20% down to 10% charge. That amount leaves me a buffer for unforeseen events.

• if you do get stuck without enough charge to get to the next charger Do Not run the battery to zero in some futile attempt to get there. Stop. Call a tow truck. Have them take you to the closest supper charger. It is massively simpler and less damaging to the car to drive it onto the tow truck.

• my advice is to drive your car to a bunch of different chargers and get used to the way things work. The cure for anxiety is knowledge.
