Tesloop has incurred a combined maintenance cost of roughly $19,000 or about $0.05/mile. This cost breaks down to $6,700 for general vehicle repairs and $12,200 for regularly scheduled maintenance. [...] Tesloop estimates that a Lincoln Town Car or Mercedes GLS class combined maintenance cost to be around $88,500 ($0.22/mile) and $98,900 ($0.25/mile) respectively over 400,000 miles.

The first battery pack replacement happened after 194,000 miles. At that time, the battery pack energy capacity degradation was at ~6%, which is reasonable, but Tesla found a problem due to Tesloop’s frequent Supercharging.

Here’s the reason Tesla gave for the battery replacement:

Found internal imbalance in HV battery due to consistent supercharging to 100% from a low state of charge (SOC) without any rest periods in between. HV battery has been approved to be replaced. Also recommend that customer does not Supercharge on a regular basis and does not charge to 100% on a regular basis. We also recommend that the customer use scheduled charging to start charge 3 hours after end of drive at low SOC.

Tesloop says that it was supercharging the car multiple times a day and at 95 to 100% state-of-charge – two things that Tesla doesn’t recommend for the health of the battery pack.

The second battery pack replacement happened at 324,000 miles and Tesloop says it experienced a much more aggressive battery degradation of ~22%.

Tesla said that there was an issue with the pack:

Diagnostics show the high voltage battery assembly is not functioning appropriately. Removed and replaced the high voltage battery assembly. Replaced with a 90kw permanent battery replacement. Pushed updated firmware to ensure proper communications. Upon completion, function test was performed to confirm concern has been rectified.

Tesla repairs and reused parts of its old battery packs, which in this case were replaced under warranty.

Those actually weren’t Tesloop battery packs with the most cycles since it also has a Model X with its original battery pack after 300,000 miles. The company reports about ~10% of battery degradation.

In 2016, Princeton economist Alan Krueger made headlines with a shocking finding that nearly half of prime age men (or men ages 25 to 54) who are not in the labor force take pain medication on a daily basis. Two-thirds of those men—or about 2 million—take prescription pain medication on a daily basis.

This fall, Krueger has published a follow-up to that research, taking an even closer look at the labor force implications of the opioid epidemic on a local and national level. The new paper and data, published in the Fall 2017 edition of the Brookings Papers on Economic Activity, makes a strong case for looking at the opioid epidemic as one driver of declining labor force participation rates.

In fact, Krueger suggests that the increase in opioid prescriptions from 1999 to 2015 could account for about 20 percent of the observed decline in men’s labor force participation during that same period, and 25 percent of the observed decline in women’s labor force participation.

The labor force participation rate [...] has been declining since the early 2000s, reaching a near 40-year low of 62.4 percent in September 2015.
