Are chevrons still cool? Maybe that’s why this sequence is like this? 
I noticed this from a sequence of mine up in Fernandina Beach last year. I’m driving eastbound on Centre St. It should be a smooth sequence.
Was this something goofy with how the Garmin Virb Elite recorded the GPS data? Or maybe something on the Mapillary side? I know I’ve seen problems that to me seem similar. But that’s just a similar symptom. It may not be the same problem.
