What are the advatages and disadvatages of commuting with bikes comparing to cars?


assistant
There are several advantages that matter a lot to me personally. Bikes are much cheaper than cars, and don't require subsequent payment for gas and insurance. Finding a parking space and paying for parking can also be a concern for cars. Commuting by bicycle for half an hour to an hour every day can relax my mind. As for the disadvantages, I can bike with caltrain/bart to commute between different cities, but it is inevitably slower than driving. Also, rainy days are very unfriendly to biking, which happens a lot these days.
