Removing them requires two very vigilant people. Also getting hit by a bus is arguably better than life-long listleness caused by lyme disease which might be inheritable to your future children.
You'll feel it itching after it digs in. Just be vigilant in the shower and use a loofa or other abraisive scrubber. Fingernails work perfectly fine as well.
Of the literally thousands of ticks I have had to remove over the years, probably less than 5 were ever left on for up to 48 hours. Most people will scratch them loose accidentally.
I went to the ER once to have a tick removed. I felt absurd doing so, but I simply couldn't reach it properly, and I had no one else around to take care of it.
Baby ticks can still carry Lyme, and can infect you with their bite.
