4. For maximum monetary gain, I'd be in favor of Tesla reducing the cost of the Ludicrous option upgrade over the next decade. If they lower the cost $750 every 6 months for new cars and for every 6 months an old car has existed and an additional $500 for every 20,000 miles the car has driven with a floor of $3,000 until the warranty expired and then there would be no floor price (just the miles and age prices), then a 60,000 mile 2 year old car Ludicrous upgrade would cost $5,500 to upgrade, and a 100,000 mile 3 year old car Ludicrous upgrade would cost only $3,000 to upgrade, and a no-warranty 4 year old car with 80,000 miles on it would cost $2,000 to upgrade (all for cars purchased today), and for cars purchased two years from now, drop another $3,000 from that price (so $7,000 at the new order page, with all the above continual discounts too, but still with that floor of $3,000 until warranty expired).
