However, the system raises safety concerns about the ejected battery posing a hazard to bystanders and the ejection mechanism&#039;s reliability in real-world crashes.  While intriguing, the technology is not currently intended for production vehicles and is considered more of a demonstration than a practical solution.<\/p>\n        <small>This summary was generated by AI using this article\u2019s content.<\/small>\n\n                    <h4 style=\"font-weight: 600; margin-top:10px;\">Read Next<\/h4>\n          <ul class=\"aqs-related-posts\">\n            <li class=\"aqs-related-item\">\n            <a href=\"https:\/\/www.dubicars.com\/news\/ev-vs-ice-car-crash-safety-repair-cost-details.html\" class=\"aqs-related-link\">\n                <img decoding=\"async\" width=\"150\" height=\"84\" src=\"https:\/\/d3jvxfsgjxj1vz.cloudfront.net\/news\/wp-content\/uploads\/2024\/01\/21104125\/ev-vs-ice-car-crash-safety-5-150x84.jpg\" class=\"attachment-thumbnail size-thumbnail wp-post-image\" alt=\"\" srcset=\"https:\/\/d3jvxfsgjxj1vz.cloudfront.net\/news\/wp-content\/uploads\/2024\/01\/21104125\/ev-vs-ice-car-crash-safety-5-150x84.jpg 150w, https:\/\/d3jvxfsgjxj1vz.cloudfront.net\/news\/wp-content\/uploads\/2024\/01\/21104125\/ev-vs-ice-car-crash-safety-5-300x169.jpg 300w, https:\/\/d3jvxfsgjxj1vz.cloudfront.net\/news\/wp-content\/uploads\/2024\/01\/21104125\/ev-vs-ice-car-crash-safety-5-1024x576.jpg 1024w, https:\/\/d3jvxfsgjxj1vz.cloudfront.net\/news\/wp-content\/uploads\/2024\/01\/21104125\/ev-vs-ice-car-crash-safety-5-768x432.jpg 768w, https:\/\/d3jvxfsgjxj1vz.cloudfront.net\/news\/wp-content\/uploads\/2024\/01\/21104125\/ev-vs-ice-car-crash-safety-5-1536x864.jpg 1536w, https:\/\/d3jvxfsgjxj1vz.cloudfront.net\/news\/wp-content\/uploads\/2024\/01\/21104125\/ev-vs-ice-car-crash-safety-5.jpg 1600w\" sizes=\"(max-width: 150px) 100vw, 150px\" \/>                <div class=\"aqs-related-title\">\n                    EV vs ICE In A Car Crash: Which Is Safer?                <\/div>\n            <\/a>\n        <\/li>\n            <li class=\"aqs-related-item\">\n            <a href=\"https:\/\/www.dubicars.com\/news\/evs-better-for-flood-than-petrol-cars-details.html\" class=\"aqs-related-link\">\n                <img decoding=\"async\" width=\"150\" height=\"84\" src=\"https:\/\/d3jvxfsgjxj1vz.cloudfront.net\/news\/wp-content\/uploads\/2024\/05\/01194119\/003-motor-mythbusters-electric-car-flood-tory-driving-in-150x84.jpg\" class=\"attachment-thumbnail size-thumbnail wp-post-image\" alt=\"\" srcset=\"https:\/\/d3jvxfsgjxj1vz.cloudfront.net\/news\/wp-content\/uploads\/2024\/05\/01194119\/003-motor-mythbusters-electric-car-flood-tory-driving-in-150x84.jpg 150w, https:\/\/d3jvxfsgjxj1vz.cloudfront.net\/news\/wp-content\/uploads\/2024\/05\/01194119\/003-motor-mythbusters-electric-car-flood-tory-driving-in-300x169.jpg 300w, https:\/\/d3jvxfsgjxj1vz.cloudfront.net\/news\/wp-content\/uploads\/2024\/05\/01194119\/003-motor-mythbusters-electric-car-flood-tory-driving-in-1024x576.jpg 1024w, https:\/\/d3jvxfsgjxj1vz.cloudfront.net\/news\/wp-content\/uploads\/2024\/05\/01194119\/003-motor-mythbusters-electric-car-flood-tory-driving-in-768x432.jpg 768w, https:\/\/d3jvxfsgjxj1vz.cloudfront.net\/news\/wp-content\/uploads\/2024\/05\/01194119\/003-motor-mythbusters-electric-car-flood-tory-driving-in-1536x864.jpg 1536w, https:\/\/d3jvxfsgjxj1vz.cloudfront.net\/news\/wp-content\/uploads\/2024\/05\/01194119\/003-motor-mythbusters-electric-car-flood-tory-driving-in.jpg 1600w\" sizes=\"(max-width: 150px) 100vw, 150px\" \/>                <div class=\"aqs-related-title\">\n                    Are EVs Better For Floods Than Petrol Cars?
