My workplace has parking. If it’s full, the zone 3 ticket would be prohibitive for sure. That brings up another factor: I have to leave before 7 AM or I’m not guaranteed to arrive on time via metro. The delays are way too unpredictable, so I need to leave time for those. Typically when I do drive it’s because I haven’t left by 7 and can’t trust I’d arrive by 8:15 due to unforeseen delays (this includes the walking parts, tbf).
