Between 8am -9am weekdays, there are 30 minut gaps between outbound M cars at Church street station. I now drive half the time, because I've had to race home to get the car in order to get to work on time. I punch a time clock and my job depends on being on time.
Between 7pm-9:30pm the inbound M at Stonestown regularly has a 60 or 70 minute wait time. I've had to call home and get a ride numerous times.
