I noticed the hourly labor rate is $175 for Tesla Service per my annual service invoice. How much of that actually goes to pay for labor? I'd be pretty happy if the service techs see >= 50% of that, but I doubt this is the case. I understand that there's some overhead baked in there like paying for utilities, a service manager/advisor, etc. But IMO that overhead shouldn't exceed 30-40%. Anyone able to provide some insight to justify the $175/hr rate?
