NJT used to run a lot more service on the 171 until the Jitneys started running, I believe some time in the 80s. It used to run every 20 mins on Saturdays. I believe this is one instance where a private enterprise, although shaky, just ran a better business model than NJT by running smaller vans more frequently and less expensive along Route 4. I agree with many of the comments that they drive like maniacs, aren't necessarily well maintained. It would be great if they could get some new and safer equipment and perhaps even coordinate with NJT in that regard since there is an obvious market for this kind of service.
