I disagree and think this is sexist. That's like saying all men are dangerous and aggressive based on major damaging accidents and crime stats. While it may appear so for the majority depending on your experiences and perspective, it is not concrete and should not be stereotyped for all IMO. I'm not asking for women to get off easy; I do not discriminate against male drivers and vehicle owners and I wish that went equally for both genders.
Every male person I've ever lived near usually had their wives, daughters, or girlfriends cleaning their cars. For people on the outside, it looked as though they themselves were carefully maintaining their vehicles. Many men I know borrow their wives, daughters, or girlfriends' cars and rough them up because they accuse the women of "babying" them too much or do not want to risk dirtying or damaging their own vehicles. I know men who have been scammed by shady mechanics and dealers just as frequently as women (unintentionally: I don't believe anyone signs up to let themselves be scammed). I know men who do not wash their vehicle unless they are selling it, or push come to shove, will only wash it once a year or two. I know men who are afraid to admit that they don't know much about vehicle maintenance because these stereotypes are pushed so much they feel ashamed for not knowing when the fact of the matter is, whether a driver is male or female, they will learn when they have an opportunity to do so eg. a relative or friend to show them the ropes, legit mechanics etc. and not everyone has such opportunities available. I know men who will admit to once driving in the same manner they see some female & male drivers driving because they too, were once unfamiliar with the roads and the vehicles and afraid. Both men and women are human and are capable of many of the same faults. When it comes to vehicle owning, driving, and maintaining I think it can go either way with each person you meet.
I don't understand why this has to be stereotyped. I would not hold a "lady driven" vehicle any higher or lower than a vehicle without that claim. When you see the car and get the details yourself then you can make accurate judgments.
