Comal County, TX — July 14, 2024, David Castillo was injured due to a motorcycle accident shortly before 11:30 a.m. along Interstate Highway 35.
According to authorities, 25-year-old David Castillo was traveling on a westbound Honda motorcycle on I-35 in the vicinity southwest of Rusch Lane when the accident took place.
Officials indicate that, for reasons yet to be confirmed, a westbound Tesla Model Y made a lane change at an apparently unsafe time. A collision consequently occurred between the right side of the Tesla and the left side of the motorcycle.
Castillo reportedly sustained serious injuries over the course of the accident. He was transported to a local medical facility by EMS in order to receive necessary treatment. Additional details pertaining to this incident are not available at this point in time.

Crashes involving motorcycles and lane-changing vehicles happen fast—but that doesn’t mean the causes are unclear. When a rider ends up seriously injured, it’s not just about who moved into which lane. It’s about whether the situation has been examined from every angle.
Did the authorities thoroughly investigate the crash?
A collision during a lane change should raise questions about signaling, mirror use, and whether either vehicle had time or space to react. Investigators should have reviewed lane markings, impact points, and any witness accounts to understand how the vehicles were positioned relative to one another. If that work wasn’t done—or if the focus was limited to what happened after contact—then important context could be missing.
Has anyone looked into the possibility that a vehicle defect caused the crash?
In a vehicle like a Tesla, the role of advanced driver-assistance systems can’t be ignored. A glitch in blind spot monitoring, automatic lane changing, or driver alert systems could lead to a move at the wrong time. On the motorcycle side, even something as simple as mirror vibration or turn signal malfunction could affect how the situation unfolded. If either vehicle was assumed to be functioning correctly without inspection, that’s a risk.
Has all the electronic data relating to the crash been collected?
Teslas are rich with data—everything from steering input to lane change timing to camera footage is potentially retrievable. That could confirm exactly when the lane change began and whether the vehicle detected the motorcycle. The Honda likely has less onboard data, but helmet cameras or phone GPS apps may help establish speed and location. If investigators haven’t reviewed those sources, then a major piece of the puzzle may still be untouched.
A serious motorcycle injury isn’t just about what happened in a split second. It’s about whether anyone took the time to understand how that second became unavoidable.
Takeaways:
- Lane-change crashes need full review of positioning, signaling, and available space.
- Malfunctions in driver-assist systems—especially in tech-heavy vehicles—must be ruled out.
- Tesla system logs and other digital evidence may clarify what the vehicle “saw” and how it behaved.
