Three of the four seats in that car are empty, and they always were.
Selling one of them should have been the easiest marketplace in transport. It worked in France, held in Spain, and failed nearly everywhere else it was tried.
Two in the front, three places behind them. This is the whole supply side of the market.

A verified phone number did the work
A verified phone number and a rating did the work an entire industry could not.
- A verified phone number and a rating did the workThe product problem was never routing: it was making two strangers legible enough to each other that one would get into the other's car.
- The profile as a contractStated preferences — how much conversation, smoking, luggage, music — turned an awkward negotiation into a filter.
The match is settled before the engine starts. What the platform sold was recognition, not routing.

Rocket Internet gave it eighteen months
A dozen-odd countries in a year, and a closing notice in the second.
- Rocket Internet gave it eighteen monthsTripda launched across a dozen-odd countries in 2014 and closed in 2016 — a deliberate machine for testing a model quickly in many markets at once.
- The launch machine, and what it is built to measureSimultaneous multi-market launches are an instrument: the metric is which corridor reaches liquidity, and everything else is closed.
The instrument measures corridors, and closes whatever does not tip inside the window.

The three readings of an empty field
What the seat was competing with
The cheap seat was never owned. It was squatted.
- Germany deregulated its coaches, and the cheap seat stopped being scarceThe 2013 liberalisation of long-distance coach services created an alternative at a price the carpool had assumed it owned.
- Where the train already winsOn corridors with frequent, fast rail the shared car is competing on price alone, and on price alone it is fragile.
- The second car, and the countries without oneHousehold car ownership decides how many potential drivers exist before any app is written.
The category owns no infrastructure. It borrows this: a car park off a trunk road where two strangers agree to meet.
