Is it permissible to pay money to someone who helps obtain a driver's license for a person with weak eyesight, in order to alleviate the suffering of not having a car, while intending to exercise extreme caution and use it only when absolutely necessary?

Traffic laws and their standards determine eligibility for a driver's license for the benefit of people and drivers. It is not permissible to violate them or to pay money to circumvent the law, as this is considered a forbidden bribe. The questioner must avoid that and endure the difficulty of transportation, as that is better than exposing himself and others to accidents.
