Why this exists
A software studio, built in daylight.
One way to build something of your own is nights and weekends, around a job. I chose the other way: delivery blocks on my own schedule, then software, events and clients in the hours between, with the car and the numbers on a public record.
Paddock20 is a software studio. The Test Track is its proving ground, and Case 01 is one 2024 Model Y.
The data
Three questions. One car. 50 days.
- How much does it cost to charge a Model Y? 41.7¢ for each kWh that reached the battery. That is 12.2¢ a mile for energy. 7.47% of the energy drawn never reaches the battery.Measured
- How much of the driving is FSD (Supervised)? 95.1% of this car's miles. FSD (Supervised) needs an attentive driver for every one of them. What it costs by the mile is a line on the Ledger.Measured
- Is a Model Y good for Uber Eats and Instacart? One driver, day by day: the charging, the delivery apps' own counts and miles, and the income by channel, slow days included.Measured
Income, worked out
On the apps' clock, this car's delivery days pay about like a $57K job.
Net dollars an hour, after payroll tax and the car's running costs, before income tax. The job counts every hour it takes: 50 hours a week on site plus a daily commute of 80 miles. This car's hours are the apps' own clock. The $25 an hour target would pay about like a $60K job.
Net dollars an hour
This car's bar pools 12 of the Record's 16 delivery days, the ones with the car's own miles; the line marks its best and worst day. The Gridwise bars use Gridwise's 2025 driver data (101,709 Uber Eats drivers, 20,538 Instacart shoppers) and a pace it does not publish, so read them as a scale, not a measurement. The job and its pay levels are examples. These are this car's days, not an average and not a promise to anyone. Every bar is modeled.

How it stays honest
Measured, modeled or stated.
- Measured
- From the car, a document or an app's own screen.
- Modeled
- Worked out from measured figures.
- Stated
- My word, with no document behind it.
The build fails rather than publish a figure that cannot be sourced, so the unflattering numbers stay: depreciation, charge loss, cold range. A figure that changes later carries a dated correction. If a company gives me something to use, or a link pays me, the page says so beside it. FSD (Supervised) is driver assistance and needs an attentive driver.
