COVID-19 saw a massive uptake in cycling across the UK and around the world. With public transport capacity reduced and people seeking socially distanced ways to travel, bikes became an essential mode of transport for millions. Yet despite this surge in cycling, safety remains the single biggest barrier preventing more people from choosing to ride.
Studies consistently show that the fear of being hit by a vehicle, not fitness, not weather, is what stops people from cycling. So how do we make roads safer for cyclists without waiting decades for infrastructure to catch up?
The Nudge Theory
Behavioural economics tells us that small, subtle changes in the environment can have a profound effect on how people behave. This is known as "nudge theory" - the idea that indirect suggestions and positive reinforcement can influence decision-making just as effectively as direct enforcement.
One of the most powerful nudges discovered by researchers is the "watching eye effect." When people feel they are being observed, they behave more carefully, more considerately, and more lawfully. This phenomenon has been demonstrated in countless studies across different contexts, from reducing littering to increasing charitable donations.
REBO's Watching Eye
The watching eye effect is at the heart of REBO's design. By incorporating prominent eye-like elements into the camera's form, REBO creates the illusion of being watched for drivers who approach cyclists from behind. This subtle visual cue nudges drivers to give cyclists more space, slow down, and drive more carefully.
The science behind this is well-established. A landmark bike theft study demonstrated that placing eye-like images near bike racks reduced crime by 35%. The mere suggestion of being watched was enough to dramatically alter behaviour. We took this insight and applied it directly to the cycling safety challenge.
Transport for London has also explored the watching eye concept in their campaigns, recognising the power of perceived observation to improve road user behaviour. The principle works across cultures and contexts, making it a universally applicable safety tool.
Even in the world of autonomous vehicles, companies like Jaguar Land Rover have experimented with adding eyes to their self-driving pods to make pedestrians feel acknowledged and safe. The human brain is wired to respond to eyes - it is one of the most primal and powerful visual cues we have.
Our product team took direct inspiration from animal eyes found in nature. Many species have evolved eye-like markings to deter predators - a phenomenon known as eyespot mimicry. We brought this natural defence mechanism into the urban environment, giving REBO its distinctive, natural look that is both functional and striking.
