Really? Chip seal caused the the motorcyclist to fall of into a ravine? Common, do you think speed had anything to do with this? I have no clue what you are saying, but I can assure you an excessive speed over the speed limit was the biggest factor or they were impaired.
You are probably right in this regard, the motorcyclist was probably going way too fast, and managed to slip on loose aggregate due to the speed/angle of turn (this is an assumption). The motorcyclists indeed do speed up and down that road at very unsafe speeds.
Don't get me wrong, I do not like it either, but I would never expect someone else to pay for my issues. Get over it, sure beats gravel and dirt [or bring something worthy to the table to whine about like pot holes].
Los Angeles City and County have been battling pot holes for a very long time. NPR just did a segment mentioning that pot holes are supposed to be repaired within 2-3 days of reporting, any resident of Los Angeles knows that many of these issues go un-attended for 6 months to a year, and only 10 percent of people who claim damage to their vehicles due to the potholes ever get any kind of compensation, and any injuries that have been caused by the negligence of repairing these pot holes get swept under the rug.
djconnel was right when he was talking about where the money goes. Do you re-pave a road that does not need it in the first place and cause a lot of commotion from recreational users? Or do you deal with the basketball sized potholes that plague the Los Angeles basin? I would have much preferred that CalTrans left the road (that was completely fine) alone - and taken the time and money to fix areas where there are real problems with road conditions and infrastructure.
