Those tires looked bald and that car had been sitting there for two to three years. Never mind the garbage and the funk, at the very least he needed to replace those tires and have the systems checked before taking a baby out in that car.
it would have taken Paul all of a day to get that done and he could have cleaned the car and hit up the carwash.
at every turn he says he is hoping to impress karine with America so she stays, but thus far everything he has done has been half ass.
Karine left her comfortable position with her family and being close to her mother who seems like she helps with pierre. She is in a position where she is in anew country with no one to rely on but Paul. Paul has managed to make the situation with his mother uncomfortable so not only can he not stay there, he apparently cannot even be in her house. Less than a day after they land, Paul loses his shit on one of the only two people she knows in a brand new country. If there was ever a thought that Paul might be able to sweet talk his way into his mother's house that illusion is over.
I don't think karine should expect Paul to have a suburban tract home and good paying job in a matter of weeks, but Paul's mom is going to stop paying for that hotel in a few weeks and then they are homeless.
so, karine is in a new, unfamiliar country with a small child, shackled to a weirdo, not fully conversant in the language and is facing possible homelessness.
With just the tiniest bit of effort he could have made that car not only palatable but a really nice thing. Instead he insisted that karine and Pierre go there with him in the sweltering heat because he couldn't clean out old french fries by himself?
Id bet good money that Paul's mother would have given him money to get that car tuned up, an oil change, new tires, alignment and balancing, ac check.
Paul's mother is tough, but willing to help, particularly if it means Paul has a reliable car to get to work and to take her grandson around.
Im not sure his criminal history would allow him to work for Uber/Lyft, but could he work for instacart or door dash?
