Quit being an alarmist. I've been riding in Houston for about a year now. I started on an 800cc Suzuki Volusia, and I''m on a Harley Heritage Springer now. Riding in Houston is not that bad, and the surface streets are worse/more dangerous than the highways. You can ride in the HOV lanes, and I recommend it whenever possible.
The Harley is not bad for commuting, but my Volusia was smaller and more nimble. If I was commuting to and from work every day in Houston, I'd want that smaller, lighter bike. Any of the midsize metric cruisers, or sport touring bikes would be good choices. Hell, even a Sportster wouldn't be bad.
However, SS is right. If you don't ride, take the MSF basic riders course, get licensed, and get legal. That alone will reduce your risk of having an accident. Non-licensed riders go down at much higher rates than licensed ones. Buy yourself a mid-sized, used bike and get some miles in on a variety of roads. You can buy a good, used bike on Craigslist all day long for under $5K, and quite a bit cheaper than that if you shop carefully.
Wear safety gear. If you want to ride without a helmet, pants or boots, then more power to you. Safe riding, however, is about risk mitigation, and proper gear, to include a helmet, eye pro, gloves, boots and a jacket, can greatly reduce your risk of injury. Trust me. I got nailed when some jackass in an SUV ran a red light at a 4-way stop. I had all my gear on, and I got up and blocked traffic while my bike burned to a molten hulk in the middle of an intersection.
Be seen. Wear lighter colors, and wear reflective stuff at night. Have bright lights on your bike. Now, I'm not a fan of the hi-vis yellow and orange, but I do tend to war light colored shirts in the summer, and all my black leather, to include my vest with my association's back patch, has reflective striping sewn on it.
