If you have an idea for a feature that would be a nice improvement, this is the place to say something. Remember, Bluecar is the app for the black car industry. If there's something that would make your business better or your job easier, if Bluecar could do it, make a comment describing it.
Also, read the comments first before commenting. If someone else has described your idea, give their comment a "like" so that we know how many drivers would value that feature.
