Re. ABS, one study seemed to indicate that when drivers have ABS they tend to adjust their risk taking upward "Among a total of 747 accidents incurred by the company's taxis during that period, the involvement rate of the ABS vehicles was not lower, but slightly higher, although not significantly so in a statistical sense. These vehicles were somewhat under-represented in the sub-category of accidents in which the cab driver was judged to be culpable, but clearly over-represented in accidents in which the driver was not at fault. Accident severity was independent of the presence or absence of ABS." http://psyc.queensu.ca/target/chapter07.html http://psyc.queensu.ca/target/chapter07.html
