This incident hits close to home, literally. The Northwest Cycling Club organizes a weekly Saturday morning group ride out of Hockley, TX, which is along this Old Hempstead Hwy where this accident occurred. Typically, there will be over 150 riders of various skill levels taking part. Riders normally break off into groups of 10-20 based on avg speed, with other smaller groups such as the road race team, triathletes, etc, breaking off to do their own preferred ride-of-the-day. For several years, I was the NWCC race team director and rode this road many, many times.
Hempstead Hwy is preferred by cyclists because it is four lanes wide of smooth pavement in a rural setting, has very little traffic and has a couple public locations for parking a large amount of vehicles which can be used as a staging area. Once HWY 290 was built, this road was essentially abandoned by those traveling from Houston to Austin or College Station. Just the locals from Hockley, Waller and Hempstead use the road. There are many county roads that branch off into even more rural areas which are more isolated, more challenging and more scenic. Most group rides start off on Hempstead Hwy, branch off for longer training routes and end up on Hempstead Hwy for the last fifteen miles back to the barn, so to speak.
Being that it is a four-lane road, it is legal for cyclists to ride two abreast on it. Doing so does not inhibit motorized traffic, especially since there is so little traffic anyway. Given the width of the lanes, that there are two in each direction, and it is a straight flat road for a good section of it, I don't feel there is any need for bike lanes or bike paths.
In my opinion, the main risks of riding here are brought about by the animosity towards cyclists of rural types (bubbas) who get a kick out of harassing those, such as cyclists, who can't defend themselves against an oversized pickup. I've had coal rolled on me out on one of these rides in the past. It seems to be a rite of passage amongst bubbas with diesel trucks. What probably contributes to their sense of entitlement is that the law enforcement knows them and their families while cyclists are seen as outsiders. The locals will stick together and protect their own, unless an independent prosecutor and judge are both on the case. The local judges cannot be counted on to be impartial when judging between a local vs outsiders, IMO.
