There is a very old thread on here about 'lift sharing' or giving lifts to someone on a regular basis. That was in 2010. It's now 2024.
I have arranged to give a lift to someone for just 2 weeks. He is also of the mentality that if someone is 'going there anyway, why couldn't they take him'. When someone doesn't own a car, doesn't drive anyway, then the costs of running a car never crosses their minds nor does the fact that the more people in the car, more fuel is used up. He is 25 stone, but if he asked me to take him regularly once the 2 weeks is up, then I would need to come to some arrangement with him because it costs me a lot more money when he is in the car than when he isn't! It's a total of 60 miles for the 2 trips a week. The cost of fuel in 2010 was a great deal cheaper than it is now in 2024. Do people still run into this kind of problem and how is it dealt with in a kind way?
