i agree with you, its not silly

no it is not silly — but it is sad that you cannot feel comfy going anywhere by any mode of transport on your own— good luck

What sort of taxi’s does your area have?
Round where I am, we have black cabs with a separate compartment for the passengers, which does make it feel somewhat safer. We can also specifically order a female driver, and there is a priority pickup service for lone women, or lone children, so they don’t have to hang around on their own at night.

Does your area have anything like this? If so, use it.
If not… well then your fear is slightly reasonable. If you just have the normal car sort of taxi, sitting in the back instead of the front will reduce the chance of casual groping, but will not really help with violent attacks. Getting the bus has more opportunity for casual groping, but also more ways to deal with problems.

No, far from silly, it is very sensible. When you get a taxi you are getting into a car with a stranger, and become very anonymous to people on the street and in other cars.

If at all possible, try to always phone a head and book a taxi so the driver is aware there is a record of you being in his/her taxi. If not, try to let friends know you are taking a taxi, from where to were and the expected time you will arrive.

Anything you can do to ensure others know where you are and when will not only make you feel safer, but also will BE safer.

well it is silly in the sense that the odds of it happening to you are probably vanishingly small, but it’s not silly in the sense that it clearly does happen sometimes, so it’s not a totally irrational fear.
