I'm sticking to my bike for now too. The story of the NYC Metro employee is scary & sad. However, the repetitive motion of lots of cycling for transport with no break is taking a toll on my knees. winter is coming and I can't bike in black ice or in really bad snowstorms. For me, biking is not sustainable as my 100% means of transport. If COIVD continues, I may have to buy a car unless another option appears I haven't thought of. Sigh.
