Lane Support Systems (LSS) are getting better, but motorcycles remain one of the hardest road users for them to detect.
Because motorcycles are smaller, narrower and produce a lower radar signature than passenger cars, many Advanced Driver Assistance Systems identify them later. Research has found that motorcycle detection can be around 25% slower than for passenger cars in equivalent blind spot scenarios. That delay can be critical once a lane change has already begun.
Recognising this challenge, ANCAP SAFETY‘s 2023-2025 Safety Assist protocols introduced specific testing of LSS using motorcycle targets. Vehicles are now assessed on their ability to detect motorcycles during overtaking and lane-change scenarios, encouraging manufacturers to improve performance.
The technology is improving through better radar, cameras and sensor fusion, but it is still far from perfect.
