It seems like a coincidence. But abandoned cars are common. I have no info in this abandoned car case, but a very common thing is if you are in a single vehicle crash and a bit under the influence of something, the smart thing to do is just leave vehicle and go home until nothing detectable is in your blood. Leaving car, and getting yourself out of there, and having a police ordered tow to an impound lot is way way cheaper than a under the influence hit if you remain with vehicle and wait for cops.
Or alternately you could just be a bit shocky from being in an accident, leave car intending to get it in a couple of days.
I dont get what the coincidence is? Except an observational bias (we all have them). probably 100 white elantras drove by that exact spot without crashing the past couple of days.
