You need to be going around 11km/s to escape earth's gravitational field. In order for the earth itself to escape the sun's gravitational field it would need to be travelling 42km/s but it's only going 30km/s.
This thing hurtling through space towards us is going 60km/s so yeah if you went that fast you'd shoot off into space with neither the earth nor sun holding you back.
