There's no doubt that easy access to cars has enabled a lot of activities in the last 50-70 years which weren't possible when people had to rely on trains and buses. It's also hit rural buses in particular very hard, so that the public transport in rural areas that don't happen to have a railway is generally far worse than in the heyday of the bus in the mid-20th century. And it's undoubtedly true that many people suffer from the mass use of cars, particularly those who live in urban areas and suffer from accidents, congestion and pollution while often not needing to run a car themselves as urban public transport may still be good enough to meet their needs.
But for reasons including CO2, local emissions and shortage of fossil fuels the petrol or diesel car will be largely extinct by the middle of this century. There will be some mix of battery and hydrogen replacements, but on their own these do not solve the congestion problem and only partly solve the pollution problem (still particulates from tyres). I hope also there will be things like better cycling facilities and integrated public transport with greater capacity and frequency, along with land use planning that connects housing and employment better to those faciilities, and that together these will cater for most people's mobility needs. However, particularly if the cars happen and the other measures don't, some may find their lifestyle choices are no longer viable or at least much more costly.
