GreenMobility targets 14,000 new Danish users by renting to 17-year-olds
GreenMobility is letting 17-year-olds rent cars in Denmark’s two largest cities, testing whether telematics can safely open a traditionally high-risk demographic to the European car-sharing market.
GreenMobility will allow 17-year-olds to rent its vehicles in Copenhagen and Aarhus, becoming one of the first European car-sharing services to target this age group. The company expects the policy change to bring in 14,000 new users. Young drivers will be restricted to the firm’s smallest vehicle, the Renault Zoe, and must obtain parental permission to use the app.
The launch relies on a recent shift in Danish road safety laws. Since July 1st 2025, 17-year-olds in Denmark can drive unaccompanied between 5am and 8pm, though they require a chaperone aged 24 or older with at least five years of driving experience outside those hours. GreenMobility has installed digital locks on its fleet to prevent rentals from being started between 7.45pm and 5am. "If they are still driving at 20:01, we won’t lock the car, as that would be too dangerous," said Kasper Gjedsted, GreenMobility’s CEO.
For the car-sharing industry, insuring drivers under 18 is typically prohibitively expensive, leading most competitors to impose hefty surcharges or outright bans. GreenMobility and its insurer analysed the specific risks and concluded that 17-year-olds do not show a higher accident rate than 18-year-olds. According to Gjedsted, the teenagers actually drive "surprisingly well".
Rather than passing higher insurance costs onto young users, the company is leaning on its internal telemetry to mitigate risk. GreenMobility’s fixed pricing model means 17-year-olds will pay the exact same rates as older customers. "If they drive too fast, we’ll know right away. We can then either send them a warning or block them from the system," Gjedsted said. Warnings are usually sent after the trip ends, but can be dispatched while the car is moving in extreme cases.
Users will be reminded of the rules before each trip starts. The broader regulatory framework also enforces strict boundaries: driving abroad is illegal for 17-year-olds, unaccompanied driving outside legal hours carries a 3,000 kroner fine, and all new licence-holders face a zero-tolerance policy on driving under the influence for their first three years. By pairing these legal guardrails with real-time vehicle monitoring, GreenMobility is testing whether younger demographics can be a viable market segment for urban mobility platforms.
