Re: Different car, different expenses
Your post has a lot of speculation in it, how about looking up the actual numbers?
[more trips to gas stations] A Tesla 3 has a range of over 200 miles. I can't imagine many people that drive longer than that day-to-day, can you? Maybe if you are a courier driver, or in sales with a large territory.
[cost to charge at home] The cost of full charge at home is around $6, depending on where you are. Let's double that to give a range comporable to your standard gas guzzler and we're sitting around $12 for a full tank. Not bad.
[Cost to install a charger]. This is be anywere from around $700 if everything goes your way through to $4000 in the worst case.
There you go - wasn't too hard to work out. Now you said these expenses "might prove higher than a conventional car" - how did you come to that conclusion, it doesn't seem to be supported by the numbers?
