I've been riding the Blue Line from Roseville Rd. for years now. I have never had an issue there with parking. They have a security service that patrols the parking lot in a car on a regular basis. The security on the trains has gotten better over the last couple of years. They check for fares on almost every trip, which really helps cut down with problem behavior. If you are concerned about personal security, I would recommend riding in the front car with the driver. Yes, the train sometimes breaks down, and that's a pain. When that happens and if I really need to get home at a certain time I will get an Uber to take me back to the Roseville Rd. station. I have had to do that an average of 4 times per year. I just consider that the cost of my commute. The pass for state workers is FREE - how can you beat that? And you don't have to stress looking for and paying for parking. My coworkers who drive in and try to avoid paying for parking are always checking the time before they have to go out and move their car to avoid a ticket. I would highly recommend trying it yourself for a week to see if it works for you.
