Quote from the Forbes article:
"If you're driving 15,000 miles a year in your Tesla your fuel bill will come to about $450. That's a hefty $1,750 savings over gasoline, but then again, the Tesla does cost around $75,000, and most of that fuel savings will be wiped away when you have to shell out $12,000 to replace your battery after five years or so."
Can those incompetent journalists not do their research and go on Tesla's website to check the battery warranty?!
And if you take good care of your battery, and your needs are not critical up to maximum range, then it will last a lot longer than the warranty. This was one more reason for me to get the 85kWh battery. In ten years, if the range is only 80% of what it was from new - who cares? And by then there will be chargers everywhere in Hong Kong, so it won't be an issue at all. I am not even sure those batteries in my car will ever be changed, if so - maybe once. I will keep the charge between 20% and 80% as much as I can, and they should last a long time.
