I drive from Baltimore to either DC or somewhere in central/northern Virginia about 3 times a week for work (I am lucky in that I am usually able to schedule meetings around 10AM). I check the time to leave on google maps the night before and set my alarm for 30 minutes before the time it says I need to leave. In the morning I put the destination into maps and go about getting ready/checking emails until the ETA is right. I’d say I usually have about 40-60 minutes in the morning until I need to leave unless there is rain. On the reverse as long as I’m past 495 before 3:30 pm and drive through the city/skip 695, there is usually no traffic.
