current path of human evolution

Since a very large proportion of human pregnancies are unplanned, I
would expect that the most predominant traits which are currently being
selected for in future generations are those connected with an
inability (perhaps economic) or unwillingness to use contraception
correctly.

According to this theory, the human species is probably rapidly
becoming more and more risk-tolerant and impulsive since such traits
would lead to a propensity to unsafe sex. Hence gambling could
continue to grow very rapidly, and (if future generations continue to
drive), roads may become more and more dangerous.

Human evolution may have reached an interesting path because the traits
most conducive to reproductive success are traits that are not
generally considered desirable. However, such traits (risk-taking,
impulsiveness) may come to be seen as desirable, inasmuch as desired
personality traits are also determined by evolution.

Has there been much professional speculation or research as to how the
recent advent of contraception is likely to affect human evolution?
