This year, that got bumped up to about 12 miles (work moved, not me). At that sort of mileage, it takes much longer to bike, and doing it consistently 5x a week with a physical job is iffy. Not to mention, bike infrastructure to that location is much worse, mostly because the only option runs along a 6-lane road, and resulted in me crashing due to road debris in the dark. Bills from that incident could have bought me a car.
Other options are mainly limited to public transport (buses). Typically takes me about 2 hours one-way, including wasted time at the start of a shift.
Then there are cars. Guaranteed to save me a minimum of an hour a day, with much lower chances of personal injury.
