Do aviation accidents attract the lamentations and attention because of their rarity? Calls to close the airport because of the risk comes to mind, whereas a B Double or car driving into someone's bedroom is just another all too common event we accept.
Perhaps some statistics would help with this question.
Road deaths in Australia over the last 5 years average around 1200 per year (

Commercial aviation deaths in Australia over the last 10 years average around 3.6 per year (

We just exceeded our average with one prang, and we don't yet know why it happened.
Obviously, the ideal goal for both road and air would be zero, but we don't live in an ideal world.
We spend billions on road safety, and yet we lose so many souls. Road transport tends to be regarded as a "right", but air transport a "privilege". If we trained and licensed road drivers in the same way we train and licence pilots, and if we subjected cars to the same level of roadworthiness that we subject aircraft, and if we build roads with the same levels of safety margins that we build airports, maybe we could significantly reduce the road toll.
But because we as a society regard road transport as a civilian "right", the economic and societal cost would be unacceptable. So we put up with the road toll.
Aviation is different. It is a privilege, and along with the "horror factor" mentioned above, it is expected to be perfect. Zero accidents. That's why a normal go-around by a commercial airliner is reported in the news as "seconds from disaster", when we all know that every car on a road is constantly "seconds from disaster", and an airliner actually never is.
