Platforms built the gig economy. Now they’re losing the people who run it.
A peer-reviewed study finds rideshare and delivery drivers are disengaging in waves. The fix, researchers say, is design, not just pay.
On 12 July 2026, a team of researchers published a study in Physical Sciences (PHYS) that asked a deceptively simple question: why are sharing-economy drivers logging off? The answer, drawn from a survey of more than 4,000 couriers and rideshare operators across nine markets, is that disengagement is not principally about wages. It is about design.
The paper arrives at an awkward moment for the platforms. Uber, Lyft, DoorDash, Grab and Deliveroo have spent the past three years competing on driver incentives, signing bonuses and fuel surcharges. The findings suggest they have been tuning the wrong dial. According to the researchers, what drivers are responding to is not how much they earn per trip but how the apps treat them between trips: opaque algorithmic decisions, abrupt incentive shifts, and a sense that the platform owes them nothing when the work stops.
The drivers who can switch off, do
The study's central finding is structural. Rideshare and delivery drivers operate in an unusually fluid labour market. They can log off, switch apps or stop working at any moment, making engagement unpredictable. Companies typically respond with short-term levers: surge pricing, quests, streak bonuses. The authors argue these levers create a relationship that feels transactional on the platform's side and precarious on the driver's. The result is a labour force that treats each app as interchangeable and each shift as a one-off decision.
The numbers are stark. Drivers surveyed reported a 38% decline in weekly active hours over an 18-month period, with the steepest drop among those who had been on a platform for between six and twelve months. The cohort that held steady tended to share two characteristics: predictable schedules and a sense that the platform's communications were honest about upcoming changes.
What actually keeps drivers around
The researchers tested seven interventions, ranging from upfront fare transparency to flexible scheduling and in-app mental-health resources. Three moved the needle in a statistically meaningful way. First, predictable scheduling windows, even when pay was held constant, reduced churn by roughly a fifth. Second, transparent notice of upcoming algorithm changes, sent at least seven days in advance, improved retention among drivers in markets with active union activity. Third, giving drivers control over which trip types they could accept (long fares only, short fares only, no airport runs) increased the number of trips completed per session without changing total hours worked.
Pay mattered, but less than the platforms assume. A 7% per-trip increase in one market produced a measurable but short-lived uptick in active hours, after which engagement returned to baseline within six weeks. The authors interpret this as evidence that drivers discount future earnings heavily against present working conditions, a finding consistent with behavioural research on gig labour but rarely acted on by the platforms themselves.
The structural read
What the platforms have built, in plain terms, is a system that extracts labour on the worker's time and subsidises itself with the worker's uncertainty. The apps treat each session as a transaction to be priced; workers respond by treating each session as a transaction to be negotiated. The structural mismatch is not new, it has been described in academic labour economics for the better part of a decade, but the PHYS study is one of the first to test specific design fixes at scale rather than simply documenting the problem.
The commercial logic is also shifting. With several major platforms reporting margin compression in 2025 and 2026, and with delivery density falling in mature markets, the cost of churn has become a board-level concern. A driver who logs off and does not return is not just a missed fare; they are a marketing liability, because their absence is visible to other drivers in the same market and depresses the next sign-up's expectations.
What to watch
Two things will determine whether the findings change anything. The first is whether any major platform adopts the design recommendations, or whether, as has happened before, they are quietly absorbed into marketing copy while operational practice remains unchanged. The second is regulator behaviour. The European Union's Platform Work Directive, which entered force in late 2024, requires platforms to disclose algorithmic management practices and, in several member states, to grant workers a presumption of employment. The PHYS study gives regulators a clearer empirical basis to argue that specific design choices, not just outcomes, are within the scope of intervention.
For drivers, the practical takeaway is sharper. Pay rises are quickly absorbed. Schedule predictability, advance notice of algorithmic changes, and control over which trips to accept appear to be the levers that move retention. Platforms that want a stable workforce may have to offer it.
Desk note: Monexus framed this as a design problem rather than a wage problem, following the study's own emphasis on behavioural and structural levers. Wire coverage so far has tended to lead on pay and incentives; the underlying finding is that those are necessary but not sufficient.
