What Are The Advantages And Disadvantages Of Consumer Behavior

7.2 Results and Discussion
The model predictions to actual survey data from separate regressions using TPB and TAM variables resulted in poor Adj. R-Squared values of 0.18 and 0.29 respectively (Figure 7-2, Figure 7-3). In contrast, a high Adj. R-Squared value of 0.923 resulted for the combination of the TPB and TAM model constructs (Figure 7-4, Table 7-3), proving that the proposed Research Model is valid for the Autonomous Cars use case. This is a confirmation that a single model can not completely explain consumer behavior towards acceptance of a new technology. The TPB model relies on Behavioral and Normative beliefs of a person. It does not take into consideration the benefits, advantages and disadvantages of the technology in question. Normative and behavioral beliefs are beyond doubt critical factors that influence the final behavioral intention of consumers. However, without the knowledge of technology or technological beliefs, the model can’t satisfactorily explain consumer behavior. Similarly, the TAM model relies solely on how much the consumer is exposed to the new technology, a prototype product etc. The model comprises of 2 key constructs such as Perceived Ease of Use (PEU) & Perceived Usefulness (PU). PEU deals with the ease of getting accustomed to or how ease of using the new technology. PEU in the case of autonomous driving involves, apart from other factors, the complexity regarding insurances, burden to learn, privacy concerns etc. PU is
