Okay, so I was a little off when I said Waze would re-route someone 15 times between the missed turn on 183 and the accident site. I drove it this evening (with Sienna Plantation as my destination) and after I crossed 183, Waze told me to turn on 5 different streets to get back to my route before I left the small residential area just east of 183. It then told me to turn on Derrick Road (once I hit the gravel SFR), which would have taken me to 86 and then back to 183. It then told me to turn around in an oil patch entrance. It then told me to turn left on Soda Springs Road to go back to 86 to 183. It then told me to turn left on Pumper Road to go back to 86 to 183. It was only after I passed Pumper Road (which is not all that far from the accident scene) that it told me to continue down SFR for 2 miles (way past accident site) to 1322 to 86 to 183. I just don't think there's any way he was following Waze. I know it's hard for most of you to picture this, but basically he was driving on a 2 lane highway from San Marcos with houses, gas stations, business, etc. along the way. Once he got to 183 in Luling, the only real way to get to I-10 is to turn right on 183. Once he crossed 183, he would have briefly been in a small residential area and then that road very quickly turns to pastures, oil patches, etc. with no businesses and very few houses. If he wasn't somehow incapacitated, there is no way he could have thought he was going the right way. Anyway, hope that helps.
