Original sentence: Although speed bumps are very effective in keeping vehicle speed down, their use is sometimes controversial as they can cause noise and possibly vehicle damage if taken at too great a speed.Poorly designed speed bumps often found in private car parks (too tall, too sharp an angle for the expected speed) can be hard to negotiate in vehicles with low ground clearance, such as sports cars, even at very slow speeds.The use of speed bumps is widespread worldwide, and are most commonly found in parking lots, alleys, and other places where prevailing vehicle speeds are expected to be low
Edited sentence: Although speed bumps are very effective in keeping vehicle speed down, their use is somewhat controversial as they can cause vehicle damage and even passenger injuries if taken at too great a speed.Poorly designed speed bumps (too tall, too sharp an angle for the expected speed) are often to blame, rather than the concept in general.Some are hard to negotiate in vehicles with low ground clearance, such as sports cars, even at very slow speeds.The use of speed bumps is widespread worldwide, and are most commonly found in parking lots, alleys, and other places where prevaling vehicle speeds are expected to be low.Vehicles with high ground clearance and softer springing, such as sport utility vehicles and other nominally off-road vehicles, negotiate speed bumps much more comfortably even at greater speeds than regular passenger cars
