A study of trends in passenger car designs between 1956 and 1974 revealed major increases in the availability and use of air conditioning, power steering, and power brakes. A laboratory study was performed which determined that significant physiologic changes occur to people under the higher levels of heat and noise found in current passenger car designs, which suggests significantly higher levels of stress can be found during long drives on hot summer days in the noisier vehicles that lack air conditioning. Subjective trade-offs between discomfort and duration of exposure were obtained that indicate people were more sensitive to noise and temperature for long exposures (several hours) than short exposures (less than an hour).
