The only time I’ve seen someone riding a motorcycle in flip flops look bad ass. Jai Ho, Hindustan. Oldest/first source I was able to find (before reddit’s repost) was from Ikjot Singh Bhasin’s facebook (also reposted on Pipeburn’s fb).
I found this photo with the caption- “Nearly 100 and still wants to ride.” I have no idea where I found it or who it is, despite attempts at research. Either way- awesome lady. If anyone has info, please let me know.
