You can always call a a taxi if its urgent.
For the first, if you can’t find a job where starting 10 minutes later is not something you can negotiate, then probably you working at a low end job, in that case you shouldn’t spend your hard earned money on car payments and gas anyway.
Cars are obviously more convenient, but also more expensive and less environment friendly. Noone force anyone to give up your convenience so no need to go defensive, just consider it as an option for all the good reasons.
I would love to know your config so I can do the same.
