I miraculously survived the accident with many broken bones and got back to work in about 3 months. And now it puts a smile on my face whenever I see the term "bus factor". And it probably scared our company quite a bit because I was the only software engineer, so definitely a bus factor of 1. But our company is mainly not a software company so they managed to survive with minimal support from me until I got back.
So yeah, it can happen! Be careful when crossing the street!
